he new multi-temporal interferometry (MTI) techniques can be profitably used to study land instability hazards. The potential appears great, but the MTI-derived results are yet to be fully explored, especially those based on high spatio-temporal resolution data. Here we focus on the use of MTI for mapping and monitoring of slope and ground instabilities in open-cast mines. They represent a good target for MTI, because they are i) often very large (from few to tens of km2); ii) free of or covered by sparse vegetation; iii) require long-term (years-decades) regular monitoring. Furthermore, given the often large extent of areas affected by surface mining and life span of mines (tens of years), long-term monitoring via traditional in-situ methods can be impractical (economically and technically). However, a review of the recent literature suggests that in comparison to applications to underground mines, MTI has been relatively little exploited to investigate ground instabilities related to surface mining. One reason for this is that some portions of open-cast mines can lack measurable radar targets due to rapid changes of ground surface caused by mining operations (e.g., overburden stripping, waste material damping). We argue that this limitation can now be (in part) mitigated by the higher frequency and regularity of acquisitions provided by the European Space Agency Sentinel-1 (S-1) mission (nominally every 6 days since Oct 2016). Indeed, S-1 medium resolution C-band SAR data acquired at 6 days imply improved time coherence with respect to previous C-band missions, leading to better coverage. We also argue that the initial reconnaissance approaches using S-1 data can be suitably integrated with high spatial resolution MTI (based on e.g., COSMO-SkeyMed or TerraSAR-X imagery) to provide most valuable information for the spatial and temporal analyses of slope deformation and a sound basis for derived products ranging from early slope instability hazard identification to individual landslide monitoring. To illustrate the potential and limitations of MTI for detecting and monitoring ground instabilities induced by surface mining, we present case study examples from two large coal open-cast operations in Europe.

Landslides and potentially unstable slopes are present in almost every country of the globe. Moreover, the
population growth, with increasing impact of humans on the environment and the urbanization of areas susceptible
to slope failures implies that landslide hazard mitigation only via traditional engineering stabilization
works and in situ monitoring is no longer considered economically feasible. Given the global dimension of the
problem of slope instability, a sustainable way towards landslide hazard reduction seems to be via increased
exploitation of affordable remote-sensing systems, with focus on early detection, long-term monitoring, and
possibly early warning. In particular, satellite-based remote sensing, and especially the synthetic aperture radar
(SAR), multi-temporal interferometry (MTI), has great potential thanks to the wide-area coverage of space-borne
sensors, day/night image acquisitions and the capability to provide high precision (mm-cm), spatially dense
(from hundreds to thousands points per km2) measurements of slow displacements of the ground surface. In this
context, Sentinel-1 A/B (S-1) twin satellites of the European Space Agency (ESA), launched in 2014 and 2016,
are now providing truly global capacity for innovative, research-oriented and practical MTI applications, such
as mapping, characterizing and monitoring of landslides. The regularity of S-1 acquisitions, timeliness of data
delivery, increased revisit frequency (days) and the resulting high coherence, as well as the availability of free
imagery, facilitate a more effective and innovative use of MTI.
The main aim of this work is to compare and assess the potential of MTI based on S-1 data in slope instability
investigations with respect to MTI relying on the earlier C-band sensors (ERS and ENVISAT), as well as the
high resolution X-band sensors (COSMO-SkyMed, TerraSAR-X). This is done by considering different areas
characterized by a wide range of geomorphic, climatic, and vegetation conditions, with case study examples of
local to regional scale MTI applications comprising hill slopes in the Apennine Mts. (Italy) and in the European
Alps, and unstable slopes in two large open-cast mines of Central Europe. The results show that, by using S-1
data, MTI can now be more effective and affordable in long-term slope/landslide monitoring, early detection of
slope instability hazard, and (in some cases) in slope failure early warning.

Il progetto ha riguardato due grotte naturali del territorio pugliese_ l'Inghiottitoio di Masseria Rotolo (PU 355 nel Catasto delle Grotte Naturali della Regione Puglia), in territorio di Monopoli e Alberobello, e la Vora Bosco (PU 1613 nel Catasto delle Grotte Naturali della Regione Puglia), in territorio di Noha, frazione di Galatina (provincia di Lecce). Si tratta delle due cavità che, sebbene a profondità diverse (-264 m dalla superficie a Grave Rotolo, e -72 m a Vora Bosco, sulla base dei rilievi precedenti questo progetto) raggiungono direttamente la falda acquifera profonda, consentendo un accesso diretto alle acque e la possibilità di monitoraggi in continuo.
Le attività svolte di monitoraggio di campo hanno fornito le prime, utilissime, indicazioni sull'andamento dei percorsi preferenziali del flusso idrico nei due sistemi carsici presi in esame.

All natural waters contain dissolved minerals from interactions with atmospheric and soil gases, mixing with other solutions, and/or interactions with the biosphere and lithosphere. In many cases, these processes resultin natural waters containing solute or salinity above concentrations recommended for a specified use, which creates significant social and economic problems. Groundwater salinisation can be caused by natural phenomena and anthropogenic activities. For the former case, we can distinguish terrestrial and marine phenomena. Approximately 16% of the total are a of continental earth is potentially in volvedin groundwater salinisation. Seawater intrusion can be considered to be the primary phenomenon for study interms of groundwater salinisation. Three schematic approaches to the protection of groundwater via salinisation mitigation and/or groundwater salinity improvement are described; these approaches are the engineering approach, the discharge management approach, and the water and land management approach. The engineering approach is realised with the purpose of controlling the salinisation, optimising the well discharge with specific technical solutions and/or completing works to improve the quality and/or quantity of the discharged fresh groundwater. The discharge management approach encompasses at least an entire coastal aquifer and defines rules concerning groundwater utilisation and well discharge. The water and land management approach should be applied on there gional scale. The practical study of Apulian karstic coastal aquifers is discussed in detail. Previously experienced management difficultie sare described, as well as a proposed multi-methodological approach based on monitoring networks, the spatiotemporal analysis of groundwater quality changes, and multiparameter well logging. The core of this approach is the definition of the salinity threshold value be tween pure fresh groundwater and any fresh and saline groundwater mixture. The basic or single tools were defined to be simple, quick and cost-effective to be applicable to the widestrange of situations.

The Apulian peninsular coastline (940 km) includes many urbanized areas and coastal wetlands, the latter in same cases interested by huge touristic transformations. The region is dominated by large and deep karstic and coastal aquifers and by some minor porous coastal aquifers the coastal outflow of which create tens of coastal wetlands. They should be considered dependent by groundwater outflow and by dynamic equilibria with sea, in terms of seawater intrusion and ingression. For a long time, these areas were considered unproductive, sources of malaria, and were depopulated. During the second half of the last century, relevant reclamation works were realized, the coastal areas have assumed a role of primary importance for the social and economic development. This has led to a growing anthropic pressure along the coast that has led to a progressive deterioration of the coastal wetland environments. High vulnerability to pollution, overexploitation trend, increasing seawater intrusion effects and global groundwater quality decrease threaten the hydrological and ecological equilibria of these water systems. The collective awareness of the important role played by the transition environments, gave rise to a conceptual innovation on the protection and enhancement of wetlands.
The research is finalized to define an inventory of the regional coastal wetlands, focusing on that the role of groundwater outflow is relevant if not prevailing. For each of these wetlands were defined a number of information and characteristics based on bibliographical knowledge and field surveys. The geological and hydrological conditions were recognized. On this basis, the hydrological and hydrogeological conceptualization was ended, permitting to define a steady state hydrological balance of wetlands. The role of seawater intrusion and ingression and the role of these in terms of salinity is analyzed. The scope is to offer a global overview of these wetlands to promote a systematic approach to their safeguard.

The use of earth surface remote sensing in geology is increasing thanks to the continuous development of sophisticated sensors and the improvements in digital image processing techniques. Here we focus on new remote sensing tools and techniques capable of delivering high-resolution data for geologic hazard investigations. These include airborne imaging systems such as UAVs (Uninhabited Aerial Vehicles) and LiDAR (Light Detection and Ranging), as well as new radar sensors onboard of Earth-orbiting satellites. We emphasize the applications of advanced synthetic aperture radar interferometry (InSAR) techniques referred to as multi-temporal interferometry (MTI). With the free imagery availability from the current (since 2014) European Space Agency (ESA) Sentinel-1 mission, MTI can now be more affordably exploited for long-term (years), regular (weekly-monthly), precise (mm) measurements of ground displacements over large areas (thousands of km2). This, in turn, means improved detection and monitoring capability of landslide/slope instability, seismic and volcanic hazards.

We focus on the use of advanced multi-temporal interferometry (MTI) for mapping and monitoring of ground deformations caused by open-cast mining and hydrocarbon production. We also show how MTI can be exploited to monitor the stability of infrastructure in adjacent areas. Open-cast mines represent a good target for MTI, because they are (1) often very large (from few to tens of km(2)); (2) free of or covered by sparse vegetation; (3) require long-term regular monitoring. The operational deformation monitoring via MTI can now rely on free of charge medium-resolution Sentinel-1 data, consistently and regularly acquired by the European Space Agency (ESA) since 2014. To illustrate the application potential of MTI based on Sentinel-1 data, we present the case study of the Belchatow mine (Poland), one of the largest open-cast mines in Europe. We stress that thanks to wide-area coverage; space-borne MTI represents a cost-effective approach to monitoring ground/slope instability hazards in large open pits, as well as the stability of the associated engineering structures and facilities. On-land oil and gas fields are also often huge and ground deformations induced by their exploitations can be profitably targeted by MTI. This is illustrated through an example of MTI application from the Middle East that relies on high-resolution (3m) radar data. The example highlights the possibility of obtaining extremely dense (spatially continuous) information, which is important for monitoring complex ground deformations caused by oil field exploitation.

The 2008 M w 7.9 Wenchuan Earthquake (Sichuan, China) was possibly the largest and most destructive recent earthquake as far as the geo-hazards are concerned. Of the nearly 200,000 landslides triggered originally, many remobilized within a few years after the initial event by rainfall, which often caused catastrophic debris flows. The cascades of geo-hazards related to the Wenchuan Earthquake motivated research worldwide to investigate the triggering and mechanisms of co-seismic landslides, their rainfall-induced remobilization, the generation of debris flows, the evolution of their controlling factors, and the long-term role of earthquakes in shaping the topography. On the eve of the 10th anniversary of the 2008 Wenchuan Earthquake, we present a short review of the recent advances in these topics, discuss the challenges faced in the earthquake-related geo-hazards mitigation practice, and suggest priorities and guidelines for future research.

The Mw 7.9 Wenchuan earthquake of May 12th, 2008 shattered and induced failures on hillslopes surrounding the centre of the town of Qiaozhuang, located 250 Km NE of the mainshock epicentre. This motivated investigations on the possible occurrence of site amplification phenomena. The initial efforts involved a temporary accelerometer monitoring carried out between April and October 2009 on Weigan hill and Mount Dong, located SW and NE of the Qiaozhuang centre, respectively. The monitoring results revealed that the local geological setting, characterised by Silurian phyllites with sub-vertical schistosity (at Weigan) and by fractured Precambrian limestones (at Dong), exert major influence on the slopes resonance phenomena, with a secondary contribution due to the topographic setting. To extend the investigation on local slope response, a series of ambient noise recordings were conducted at several sites of the two hills, as well as at Mount Shizi (located NW of the town centre), which is topographically and geologically similar to Mount Dong. The focus was on the sites monitored by accelerometer stations, whose seismic records provided the opportunity to validate the outcomes of ambient noise analysis. Noise data were analysed using two approaches_ the standard Nakamura's method and a new technique based on analysis of instantaneous polarization properties, aimed at estimating ellipticity of Rayleigh waves. Data interpretation was hampered by a contingent factor, i.e. environmental conditions characterised by a strong persistent E-W polarized noise at low frequencies (below 1 Hz), and by the complex of geologic and geomorphic conditions. The latter, particularly in the case of Weigan hill, appear responsible for a considerable amplification of vertical ground motions. The repeated recordings and the comparison of the outcomes of the two techniques of noise analysis with the accelerometer data showed that the new technique provides more stable and consistent results. Furthermore, the new technique was able to reveal site resonance properties that Nakamura's method fails to recognise because of transient overlapping of different type waves. Overall, the ambient noise analysis provided evidence of i) low frequency resonance (~1 Hz) acting at the scale of the entire relief (on Weigan Hill), ii) directional amplifications at intermediate frequencies (~4 Hz) affecting ridge crests made of fractured limestone (on Mounts Dong and Shizi), and iii) higher frequency resonances (7-20 Hz), which vary at a very local scale. This information is relevant for inferring the susceptibility of local slopes to earthquake-induced failures, and hence for the collateral seismic hazard assessment in the Qiaozhuan peri-urban areas.

Lo studio ha per oggetto il rilievo di un'antica torre di avvistamento aragonese del XVII secolo, ubicata lungo la costa adriatica circa 3 km a Nord dell'abitato di Polignano a Mare, in località San Vito. La torre di San Vito si colloca nel sistema di torri di avvistamento, difesa e comunicazione distribuite lungo la costa adriatica. Il sito è molto interessante da un punto di vista archeologico_ porto naturale sull'adriatico e statio (stazione di cambio) sulla via traiana fu sede, nei secoli, di fiorenti traffici ed attività commerciali. Grazie alla particolare posizione e alla facilità di collegamento con i paesi dell'entroterra, tra il V e il VII secolo qui si insediarono i monaci basiliani. Furono proprio i monaci seguaci di San Basilio, secondo la leggenda, ad accogliere le reliquie di San Vito giunte a Polignano con la principessa salernitana Fiorenza nell'anno 801. In questo luogo i monaci, per custodire le reliquie del Santo, iniziarono la costruzione dell'Abbazia e del suo sistema difensivo_ le mura e all'interno di queste la torre masseria del XVI secolo. Successivamente, nel XVII secolo fecero innalzare una torre d'avvistamento esterna posta a difesa dell'Abbazia contro le incursioni dal mare. Su tale torre è stato eseguito un rilievo fotogrammetrico da drone a circa 70m di altezza, con una rete di controllo a terra di 15 GCP. Sono state elaborate circa 330 immagini sia nadirali che inclinate, ottenendo una nuvola di 524.607 punti con una risoluzione 0.010096 m/pix punti. Dall' intera nuvola di punti sono stati estratti il modello 3D della torre e le ortofoto delle facciate e della copertura. La particolarità di tale tecnica ha permesso di evidenziare elementi peculiari della torre difficilmente rilevabili con rilievo "a terra", data la inaccessibilità dei luoghi.

Abstract

As stated in many issues, the climate a leading cause of triggering and evolution of mass movements. Differently
from other triggering factors the climatic factors can be well defined for the past and forecasted in the short and
medium term. Therefore, the recognition of the climatic trends related to geomorphological and hydrogeological
modifications allows for a prevision of landslides and other impacts on human life.
The Fourth Assessment Report (AR4) on Climate Change (IPCC) predicts that the global sea level will rise
of 60 cm by the year 2100 in response to the warming of the oceans and melting of glaciers. This could
have a significant impact on the evolution of the environment if we take into account that coastal areas house
approximately 10% of the world population.
This paper describes an example of how climate change, and all possible related effects, played a driving role on
the triggering and evolution of a huge landslide.
The studied area is the coastal slope of the town of Vasto (Abruzzo, Central Italy) recently affected by numerous
landslide reactivations. The landslide body extends for 2 km2 from the crown zone (at about 150 m a.s.l.) towards
the coastal line. The deep-seated gravitational deformations and large landslides with submarine foots observed
on the Vasto coastline are typical of mass movements occurring along the Adriatic coast, in the Plio-Pleistocene
sequences represented by clays, sands and conglomerates with continental deposits covers.
This study shows that the historical reactivations of the landslide, as well as its scarp retrogression, are related
to transients destabilizing factors such as rainfall or snow-melting whereas oldest and deeper mass movements
were caused by various eustatic fluctuations in sea level, starting from the emergence of the slope in the middle
Pleistocene, where the sub-aerial phase of the transgressive marine succession began.
A paleo-morphologic reconstruction of the slope enabled to correlate the numerous instabilities over time to the
fluctuations in the level of the Adriatic Sea from the Middle Pleistocene to the present.
For a more complete study, it was necessary to reconstruct a "geological-evolutionary model of the slope"
that could explain the current stratigraphic features and the actual landsliding framework. The evolutionary
model has been useful to understand and explain how the variation in sea level due to climate changes and the
simultaneous lifting of the area conditioned the present morphology of the hillside, predisposing the slope to a
widespread landsliding. The results of geological-evolutionary model of the slope were validated using a Finite
Elements stress-strain analysis carried out by means of the FLAC 6.0 calculation code. The stress-strain numerical
simulations show that the first activation of the landslide Vasto would have taken about 200,000 years ago at a
rapid rising of sea level.
In conclusion, the landslide mass currently observable reflects a phenomenon of instability which was fully
activated approximately 200,000 years ago, in correspondence with a phase of high marine station. This instability
continued to evolve with local events up to the present day.

The paper reports the results of a slope-atmosphere interaction analysis performed with reference
to geo-hydro-mechanical conditions typically observed on the Southern Apennines (Italy). The aim of
the analysis is to gain some understanding in the characterisation of climatic variables employed
to identify instability thresholds in clay slopes. A seepage analysis was undertaken first, showing
that Mediterranean climates can produce significant pore-pressure changes also at depths not
usually considered to be affected by atmospheric conditions. Based on the results of the seepage
analysis, limit equilibrium analyses were carried out for a 5 m and a 20 m deep landslide, confirming
that also deep movements in clay slopes can be related to slope-atmosphere interaction.
The characterisation of climatic variables aimed at identifying instability thresholds is finally
discussed based on the analyses reported in the paper. The results show that net rainfall cumulated
over 2 and 6 months represent suitable climatic variables for the 5 m and the 20 m deep landslide,
respectively. These findings suggest that the stability of a clay slope, when referred to shallow
movements, is likely to depend on the rainfall infiltrating over a few weeks at least. When deep
movements are considered, the stability seems to depend more on the rainfall gradually infiltrating
during the most rainy seasons

An interdisciplinary research has been carried on for several years by CNR IRPI and Politecnico di Bari about the geological, tectonical, morphological and geotechnical aspects connected to the land subsidence of the Sibari alluvial coastal plain. Historical subsidence in this area is made evident by the vertical stacking of three ancient towns along the Crati river. In order to investigate the evolution and the disappearance of the archaeological site, the results of the research defined the causes of the settlements affecting the area since ancient times, while recent studies have focused on a recent component of the subsidence and addressed to the interpretation of the causes of the current subsidence rates logged in the plain by PS-INSAR monitoring .
Geotechnical modeling has been developed to investigate whether these rates are due to both water withdrawal from deep aquifers, identified in previous studies, and pumping of shallow water through a well-point system still active in a few areas at the archeological site The paper is specially addressed to assess the geotechnical modeling that has been developed to interpret the source of the current settlement rates. The model is based on an extensive set of geotechnical profiles and laboratory data. The calculation results are compared to the recent data collected by remote sensing and allow to forecast the possible evolution of the subsidence.

A high dynamic environment is typically interested by changes affecting the natural
processes and their related consequences. Landslides do not only alter the landscape,
but substantially affect human activities. When it comes to natural hazards, landslides
have been acknowledged as one of the main causes of human casualties or damage
to assets. Furthermore, economic losses to rural lands are also significant, despite often
being underrated, especially in rural areas. In not densely populated territories, the main
productive activities are in fact often based on the agricultural and pastoral resources.
We intend to propose a methodology that helps to investigate the potential loss of value
(expressed in e) of lands usually exploited for economical profit in rural areas.We test the
method on two case studies, belonging to different European Countries with very different
economical assets and geological, geomorphological, and environmental conditions.
The first study area is located in the Southern Italian Apennines, in the Molise region,
while the second area is located in Buzau County, a region belonging to the Romanian
Curvature Carpathians and Subcarpathians. Our analysis is focused not only on the
actual situation, represented by the past and present landslides, but also on potential
future scenarios for 2050. The scenarios foresee future similar socio-economical and
technological activities, with no major changes expected. The loss estimation is based
on the presence of landslides affecting the rural lands, but it also considers both a present
and future landslide susceptibility scenario. This procedure allowed the estimation of
the economic losses in the two case-study areas, highlighting how the same natural
processes might result in different economical consequences. Following our approach,
the results highlight that for the Italian case study there is a loss of 10.4% for 2007
and 9.9% for 2050 of the total land value as concerns landslides susceptibility. In the
Romanian case study, on the other hand, the loss corresponds to 29.6 and 29.8% for
2010 and 2050, respectively. In addition, the proposed procedure could be considered a
valuable methodological approach to assess landslide-induced economic losses, and be
effectively used during spatial planning activities, aimed at supporting decision makers
for a more sustainable land management.

Hypogenic caves, developed by sulphuric acid speleogenesis, are known all over the world among which the Santa Cesarea Terme caves have been included. They are four submerged caves, located along a coastal carbonate sector in Southern Italy and hosting the outflow of coastal springs of thermal mixed waters (from 21 to 33 °C). These waters derive from the mixing of three water end members_ the fresh pure groundwater of a wide karstic aquifer, the deep sulphur thermal water and the seawater. This cave system represents an almost unique case of hypogenic sea caves in carbonate environment. The thermal mixed waters have a different effect on the surrounding rocks of the caves, influencing the sulphuric acid speleogenetic process within the whole cave system. To understand the complex and overlapping natural processes acting on the development
of these coastal caves, a multidisciplinary study has been carried out. This study has integrated all the data resulting from different methods and technologies, merging morphology, structural geology, hydrogeology, hydrogeochemistry and mineralogy. This multidisciplinary study has allowed to define the main geochemical processes acting within these caves, including the cave development and the formation of the mineral concretions. After the introduction of H2S in the thermal waters, formed by the reduction of sulphates in the sedimentary deposits crossed at depth in the offshore, the oxidation occurs within the caves, producing sulphuric acid. Favoured by upwelling deep-seated thermal flows, this acid dissolves the limestone, with condensation corrosion process that involve replacement of limestone rock with gypsum. This process has resulted to be more active and remarkable within the Gattulla Cave, one of the Santa Cesarea Terme sea caves.

Sinkholes are the main hazard related to underground voids of both natural and anthropogenic origin. Instabilities developing underground may propagate upwards in a dramatic manner and reach the surface in the form of a sinkhole. The Apulia region in southern Italy is an interesting case study due to the outcropping of soluble rocks throughout the region. These rocks are affected by karst processes and have a high number of anthropogenic cavities. The latter were excavated by humans at different times for a variety of purposes. The worrying recent increase in the number of sinkhole events registered in Apulia led us to collect information on natural and anthropogenic sinkholes in Apulia. We focused on anthropogenic cavities, mostly excavated in Plio-Pleistocene calcarenites, and characterized the rock masses before using two- and three-dimensional parametric
numerical analyses to model the instability processes, with the aim of exploring the failure mechanisms that lead to the occurrence of sinkholes. The parametric studies allowed us to carry out a preliminary evaluation of the stability conditions through simple charts designed for use in the field.

Abstract

The attention of local communities and authorities was focused on the level of nitrate concentration in ground-water of a wide coastal karstic aquifer, not far from the town of Bari (southern Italy), worried about the poten-tial effect of sanitary and unsecure landfills.
Five landfills have operated from 1975, one after the other, using increasing safety and technological devices to reduce risks due to leachate leakages with consequent groundwater quality degradation.
A multi-methodological approach was conducted to define the origin of nitrate contamination.
The approach includes hydrogeological site characterization, chemical and isotopic study of groundwater and leachate, land use analysis and estimation of nitrogen contributions deriving from agricultural activities, focus-ing on the use of fertilizers and mineralogical study of groundwater suspended particles to define the origin of the iron and manganese in the water samples.
In particular, the environmental isotopes of oxygen-18 (18O) and deuterium (2H) were used to investigate the origin of water in the aquifer system of the study area. The combination of NO3- concentration with ?15N-NO3- and 18O-NO3- in water also provides valuable information for identifying different sources of NO3- to the coastal aquifer. Groundwater and leachate samples were analyzed for 13C and Tritium (3H). Previous studies have demonstrated that the biogeochemical processes occurring within the landfill environment can produce a unique composition of these isotopes and therefore they can be utilized successfully to delineate the potential leachate influence.

The Apulian peninsular coastline (940 km) includes many urbanized areas and coastal wetlands, the latter in same cases interested by huge touristic transformations. The region is dominated by large and deep karstic and coastal aquifers and by some minor porous coastal aquifers the coastal outflow of which create tens of coastal wetlands. They should be considered dependent by groundwater outflow and by dynamic equilibria with sea,
in terms of seawater intrusion and ingression. For a long time, these areas were considered unproductive, sources of malaria, and were depopulated. During the second half of the last century, relevant reclamation works were realized, the coastal areas have assumed a role of primary importance for the social and economic development. This has led to a growing anthropic pressure along the coast that has led to a progressive deterioration of the coastal wetland environments. High vulnerability to pollution, overexploitation trend, increasing seawater intrusion effects and global groundwater quality decrease threaten the hydrological and ecological equilibria
of these water systems. The collective awareness of the important role played by the transition environments, gave rise to a conceptual innovation on the protection and enhancement of wetlands.
The research is finalized to define an inventory of the regional coastal wetlands, focusing on that the role of groundwater outflow is relevant if not prevailing. For each of these wetlands were defined a number of information and characteristics based on bibliographical knowledge and field surveys. The geological and hydrological conditions were recognized. On this basis, the hydrological and hydrogeological conceptualization was ended, permitting to define a steady state hydrological balance of wetlands. The role of seawater intrusion and ingression and the role of these in terms of salinity is analyzed. The scope is to offer a global overview of these wetlands to promote a systematic approach to their safeguard.

The coastal carbonate Apulian aquifers, located in southern Italy, feed several coastal fresh springs and constitute the main local source of high quality water. The Santa Cesarea Terme cave system is almost unique case of hypogenic coastal spring caves, located along the Adriatic Sea coastline and hosting spring coastal outflow of mixed groundwater (from 22°C to 33°C) mainly of thermal groundwater due to infiltration offshore, in the sea bottom, and pure fresh groundwater due rainfall infiltration. Thermal springs and the outflow system are strictly controlled by both the discontinuity network and the karst processes involving the foreland environment. Detailed geoelectrical prospecting were carried out to bound the upflow continental area of this system, considering the geoelectrical effects of deep water mixing with different salinity and temperature close the Adriatic coast.

Where the unique natural water resource is groundwater, the attention and the susceptibility of local communities and authorities to groundwater quality degradation risks can be so high to determine relevant problems to waste management, especially for landfills in operation or to be realised. A multi-methodological approach was suggested with the purpose to clarify the role of landfill leakage on groundwater quality degradation.
The selected study area (SSA) hosts some landfills in a narrow portion of a wide and deep coastal karstic aquifer, for these characteristics to be considered a case of high hydrogeological complexity and vulnerability. News concerning nitrate and secondly iron groundwater concentration anomalously high caused concern in the population and strong local opposition to landfills.
The multi-methodological approach includes_ the hydrogeological site characterization; the chemical study and the multi-isotope characterization of groundwater and leachate; the land use analysis and the estimation of nitrogen contributions deriving from fertilizers; the mineralogical study of groundwater suspended particles to define the role of natural soil substances.
The hydrogeological site characterisation highlighted the local peculiarities of the aquifer. The chemical study was used to define geochemical features, groundwater and leachate characteristics and their macroscopic mixing.
The environmental isotopes of hydrogen, carbon, nitrogen, and oxygen were used to investigate the groundwater origin, the most relevant geochemical reactions, the existence of groundwater-leachate mixing, and the sources of anthropogenic NO3-. The land use analysis highlighted quantity and type of used fertilizers permitting to compare these with groundwater in terms of isotopic signature. The mineralogical study demonstrated the role of suspend natural particles due the presence of terre rosse (red or residual soils) in groundwater.
The approach confirmed that there are not the groundwater quality degradation effects of landfills, contributing to reassure population and institutions, simplifying the waste management.

The submarine or coastal groundwater outflow is often due or overlapped to important offshore geothermal phenomena, which contribute to modify geochemical water characteristics, sometime adding relevant gases outflow fractions.
The peculiarities of these natural phenomena create uncommon difficulties to the geological, geochemical, and hydrogeological conceptualization, the solution of which contributes to the earth knowledge, in some cases, at high depth. The study of these phenomena, call for a continuous improving of study tools, methods and equipment.
The peculiarities of these fluid outflows can create peculiar environment, of high ecological relevance and/or with important social and economic effects, also in terms of any type of geothermal energy utilisation.
The special issue is a global call for any experience of scientific relevance which is facing with the study of these phenomena from any point of view, including methodological or technological improvements, or to focus on conceptualization of peculiar study cases, and review articles which describe the current state of the art on these subjects.

The Cesine Wetland, located along the Adriatic coast, was recognized as a Wetland of International Interest and a National Natural Park. Managed by the "WorldWide Fund for nature" (WWF), it is considered a groundwater dependent ecosystem which is affected by seawater intrusion. The site was selected to test the environmental compatibility of a low-enthalpy geothermal power plant (closed loop) operating in the aquifer saturated portion with purpose to improving the visitor centre. For this purpose, the long-lasting thermal impact on groundwater was assessed using a multi-methodological approach. The complex aquifer system was carefully studied with geological, hydrogeological and geochemical surveys, including chemical and isotopic laboratory analyses of surface water, groundwater and seawater. The isotopes 18O, D, 11B, and 3H were useful to clarify the recharge contribution, the water mixing and the water age. All information was used to improve the conceptualization of the water system, including aquifers and the boundary conditions for a density driven numerical groundwater model. The purpose was to forecast anthropogenic thermal groundwater variations up to 10 years of plant working before the plant realization and to validate the solution after some working years. All results show the environmental compatibility notwithstanding the peculiar ecological environment.

Abstract
The variability of precipitation and temperature, the combined effect of which determines a decreasing trend ...
The variability of precipitation and temperature, the combined effect of which determines a decreasing trend of recharge, is critic for groundwater resources due to the overlapping with the increasing exploitation. In Campania, from the eighties to 2008 precipitation has decreased, not uniformly in the whole region; now the trend seems increasing, but this trend is highly influenced by the period 2008-2011, very rainy. In Apulia, the decreasing trend of rainfall is notable after 1980_ the droughts of 1988-92 and 1999-2001 appear to be exceptional. The Apulian piezometric trend of the last 40 years highlights the dramatic decrease of groundwater availability.
This remarkable lowering defines a widespread quantity degradation. The situation severity of groundwater resources is worsened by the effects on the quality of groundwater resources due to the salinization of the wide coastal aquifers of the whole Southern Italy.

The behaviour of natural and artificial slopes is controlled by their thermo-hydro-mechanical conditions and by soil-vegetation-atmosphere interaction. Porewater pressure changes within a slope related to variable meteorological settings have been shown to be able to induce soil erosion, shrinkage-swelling and cracking, thus leading to an overall decrease of the available soil strength with depth and, ultimately, to a progressive slope collapse. In terms of numerical modelling, the stability analysis of partially saturated slopes is a complex problem and a wide range of approaches from simple limit equilibrium solutions to advanced numerical analyses have been proposed in the literature. The more advanced approaches, although more rigorous, require input data such as the soil water retention curve and the hydraulic conductivity function, which are difficult to obtain in some cases. The quantification of the effects of future climate scenarios represents an additional challenge in forecasting slope-atmosphere interaction processes. This paper presents a review of real and ideal case histories regarding the numerical analysis of natural and artificial slopes subjected to different types of climatic perturbations. The limits and benefits of the different numerical approaches adopted are discussed and some general modelling recommendations are addressed.

Land cover is one of the most important conditioning factors in landslide susceptibility analysis. Usually it is considered as a static factor, but it has proven to be dynamic, with changes occurring even in few decades. In this work the influence of land cover changes on landslide susceptibility are analyzed for the past and for future scenarios. For the application, an area representative of the hilly-low mountain sectors of the Italian Southern Apennines was chosen (Rivo basin, in Molise Region). With this purpose landslide inventories and land cover maps were produced for the years 1954, 1981 and 2007. Two alternative future scenarios were created for 2050, one which follows the past trend (2050-trend), and another one more extreme, foreseeing a decrease of forested and cultivated areas (2050-alternative). The landslide susceptibility analysis was performed using the Spatial Multi-Criteria Evaluation method for different time steps, investigating changes to susceptibility over time. The results show that environmental dynamics, such as land cover change, affect slope stability in time. In fact there is a decrease of susceptibility in the past and in the future 2050-trend scenario. This is due to the increase of forest or cultivated areas, that is probably determined by a better land management, water and soil control respect to other land cover types such as shrubland, pasture or bareland. Conversely the results revealed by the alternative scenario (2050-alternative), show how the decrease in forest and cultivated areas leads to an increase in landslide susceptibility. This can be related to the assumed worst climatic condition leading to a minor agricultural activity and lower extension of forested areas, possibly associated also to the effects of forest fires. The results suggest that conscious landscape management might contribute to determine a significant reduction in landslide susceptibility.

Abstract
The regularity and higher frequency of acquisitions of Sentinel-1A/B (S-1) with respect to earlier ESA's ...
The regularity and higher frequency of acquisitions of Sentinel-1A/B (S-1) with respect to earlier ESA's satellite C-band sensors (ERS1/2, ENVISAT) represent clear advantages for users of multi-temporal interferometry (MTI) products. The utility of the IW acquisition mode of S-1 for regional scale slope instability detection through MTI has already been demonstrated, e.g., via studies of landslide-prone areas in Italy. In this work, we explore the potential of S-1 data for local (site-specific) scale landslide monitoring and capturing pre-failure signs of slope instability. This is done by using examples of two unstable slopes from different environmental settings and MTI through the Persistent and Distributed Scatterers processing capability of the SPINUA algorithm.
The first case regards a hilltop town in the Apennine Mts., whose stability is threatened by a large (~600 x 300 m2), slow moving deep landslide. We processed over 50 S-1A images acquired since October 2014. The comparison of the MTI results with those based on ERS and ENVISAT imagery shows that a much higher number of radar targets is obtained from S-1A data (e.g., from ~2 to 5 times higher, respectively on the landslide and in the overall area of interest, including also the town and peri-urban areas). With more targets, we can better depict the spatial movement pattern and local velocity gradients, which is important for geotechnical assessment. Furthermore, the lateral boundaries of the landslide can now be delimited in more detail, overcoming the mapping uncertainties typical in cases of very slow, deep landslides affecting urbanized areas. This offers invaluable information for local inhabitants/property owners and for engineering scale hazard assessment. Importantly, the MTI from S-1A data also revealed an accelerating trend with a nearly doubled velocity of the displacements with respect to those in the earlier period covered by ERS-ENVISAT data. The higher frequency of S-1A acquisitions (about 30/year in this case) helped highlighting the non-linearity of surface deformations within the faster displacement phase, whose timing was consistent with the increase in landslide movements detected through subsurface inclinometer monitoring and field observations. The latter demonstrated that this faster movement phase coincided with (or was preceded by) a failure of the landslide toe, which occurred in the inhabited area.
The second case represents an example of a retrospective investigation of a huge (over 2 km long, few tens of m deep) landslide, which occurred in 2016 in an important open-cast coal mine in central Europe. The apparently sudden failure disrupted the mining operations, destroyed in part the mining machinery and resulted in high economic losses. In this case, we exploited over 60 S-1A/B images acquired since November 2015. Despite the presence of spatial gaps in information (due to intensive surface disturbance by mining operations), the MTI results provided a good overview of the ground instability/stability condition within and outside the active mine. Furthermore, it was shown that the 2016 slope failure was preceded by very slow (generally 1-3 cm/yr) creep-like deformations, already detectable in 2014. Although it would not have been simple to issue a short-term warning of the impeding failure based on the displacement time series, the MTI results showed that the slope had been in the critical instability state some months prior to the landslide event. Furthermore, the spatio-temporal mapping of coherence changes in the unstable area indicated a sharp coherence loss in the last few weeks before the slope collapse.
The above examples demonstrate that by securing long-term, regular, high-frequency acquisitions over wide-areas, the Sentinel-1 mission facilitates a more effective use of MTI in slope hazard assessment. We note further improvement thanks to the availability of S-1B data (e.g., more frequent measurements to forewarn potential instability hazards). This has practical impacts on landslide monitoring activities and will aid future research on slope failure forecasting. Thanks to this and free imagery, the site-specific investigations relying on MTI will become even more feasible and cost-effective for non-scientific users (e.g., engineering geology/geotechnical consulting) and commercial services (e.g., Rheticus®).

The shorter repeat cycle (6 days since October 2016) and regularity of acquisitions of Sentinel-1A/B with respect
to earlier European Space Agency (ESA) satellites with C-band sensors (ERS1/2, ENVISAT) represent the key
advantages for the research-oriented and practical applications of multi-temporal interferometry (MTI). The
applicability of the Interferometric Wide Swath acquisition mode of Sentinel-1 (images covering a 250 km
swath on the ground) to regional scale slope instability detection through MTI has already been demonstrated,
e.g., via studies of landslide-prone areas in Italy. Here we focus on the potential of Sentinel-1 data for local
(site-specific), MTI-based monitoring and capturing pre-failure signs of slope instability, by exploiting the
Persistent and Distributed Scatterers processing capability of the SPINUA algorithm. In particular, we present
an example of a retrospective study of a large (over 2 km long) landslide, which took place in 2016 in an active
open-cast coal mine in central Europe. This seemingly sudden failure caused destruction of the mining equipment,
blocked the mining operations thereby resulting in significant economic losses. For the study, we exploited over
60 Sentinel-1A/B images acquired since November 2014. The MTI results furnished a valuable overview of the
ground instability/stability conditions within and around the active mine, even though considerable spatial gaps in
information were encountered due to surface disturbance by mining operations. Significantly, the ground surface
displacement time series revealed that the 2016 slope failure was preceded by very slow (generally 1-3 cm/yr)
creep-like deformations, already present in 2014. The MTI results also indicated that the slope experienced a phase
of accelerated movement several weeks prior to the landslide event. Furthermore, the spatio-temporal analysis of
interferometric coherence changes in the unstable area (mapped on Sentinel-2 Bottom Of Atmosphere reflectance
images processed by using the ESA Sen2Cor processor), indicated a sharp coherence loss in the last few weeks
before the slope collapse. The availability of more frequent measurements represents a key improvement for
MTI-based ground surface displacement monitoring and this will better support research on slope destabilization
processes over time and, ultimately, on slope failure forecasting.

Le forme del paesaggio pugliese sono variabili e disegnano un composito panorama geografico nel cui ambito si distinguono diverse aree caratterizzate da peculiarità geomorfologiche delimitate da confini orografici. Essendo la Puglia costituita essenzialmente da depositi carbonatici caratterizzati da diffuse morfologie carsiche, è una delle regioni a più elevata densità di ipogei con alta valenza archeologica e storico- artistica, attualmente in stato di conservazione precario, per cui, in alcuni casi viene obliterata la lettura completa dell'insediamento stesso. Il patrimonio ipogeo, molto complesso e articolato, è basato su una pluralità di processi insediativi e culturali di epoche e connotazioni diverse, strettamente integrati nel tessuto edilizio attuale. Le ricerche svolte hanno riguardato, con approccio multidisciplinare e multiscala, le diverse problematiche relative alle tipologie di ipogei, analizzando la loro ubicazione, genesi, il sistema di integrazione con la città e il possibile recupero funzionale. Il metodo di indagine è stato di tipo deduttivo

The variability of precipitation and temperature, the combined effect of which determines a decreasing trend of recharge, is critic for groundwater resources due to the overlapping with the increasing exploitation. In Campania, from the eighties to 2008 precipitation has decreased, not uniformly in the whole region; now the trend seems increasing, but this trend is highly influenced by the period 2008-2011, very rainy. In Apulia, the decreasing trend of rainfall is notable after 1980_ the droughts of 1988-92 and 1999-2001 appear to be exceptional. The Apulian piezometric trend of the last 40 years highlights the dramatic decrease of groundwater availability.
This remarkable lowering defines a widespread quantity degradation. The situation severity of groundwater resources is worsened by the effects on the quality of groundwater resources due to the salinization of the wide coastal aquifers of the whole Southern Italy.

The main goal of Theme 5 (Volume 5) is to draw attention to the variety of landslides that have an impact on communities, infrastructure and cultural heritage. This sub-theme focuses on the interaction of landslides with the built environment, whether triggered in natural or engineered slopes. The broad relevance of this sub-theme is clear and the associated socio-economic issues are particularly important given population growth and the associated demand for new and enhanced infrastructure. It provides an overview of methodologies and techniques that can be used to identify the effects of landslides on buildings, infrastructure and large engineering works, as well as cultural heritage.

Landslide investigations can now benefit from high quality information obtainable using multi-temporal interferometry (MTI) techniques (e.g., PSInSAR, SBAS) and images acquired by satellite synthetic aperture radars (SAR). MTI is only little affected by bad weather and can provide long-term (years), regular (weekly-monthly), precise (mm) measurements of ground displacements over large areas (thousands of km2), with the possibility of exploiting the same series of radar images for regional to slope-scale investigations. Spatially dense measurements can be obtained (from hundreds to thousands data per km2). Furthermore, by offering regular global-scale coverage, improved temporal resolution (from 12 to 6 days) and free imagery, the new radar satellite mission Sentinel-1 of the European Space Agency (ESA) can now guarantee wider and more efficient application of MTI to landslide investigations. In this work we demonstrate for the first time the excellent potential of MTI based on Sentinel-1 for the detection and monitoring of slope instabilities affecting small hilltop towns in the Apennine Mountains of southern Italy. The is done by comparing the MTI results based on Sentinel-1 images with those based on ENVISAT data (ESA satellite retired few years ago). The comparison shows that by using Sentinel-1 imagery a few times higher density of radar targets (measurement points) can be obtained. Thanks to this and more frequent measurement capability of Sentinel-1, landslide detection and monitoring can be more effective.

Advanced remote sensing techniques are now capable of delivering more rapidly high quality information that is sufficiently detailed (and cost-effective) for many engineering applications. Here we focus on synthetic aperture radar (SAR), multi-temporal interferometry (MTI). With radar satellites periodically re-visiting the same area, MTI provides information on distance changes between the on-board radar sensor and the targets on the ground (e.g., human-made structures such as buildings, roads and other infrastructure). The detected distance changes are thus interpreted as evidence of ground and/or structure instability. In settings with limited vegetation cover, MTI can deliver very precise (mm resolution), spatially dense information (from hundreds to thousands measurement points/km 2) on slow (mm-cm/year) deformations affecting the ground and engineering structures. Radar satellites offer wide-area coverage (thousands km 2) and, with the sensors that actively emit electromagnetic radiation and thus can "see'' through the clouds, one can obtain deformation measurements even under bad weather conditions. We illustrate the potential of high resolution MTI and explain what this technique can deliver to assist in infrastructure instability hazard assessment. This is done by presenting selected examples of MTI applied to monitor post-construction behavior of engineering structures. The examples are from Italy and include_ an earthfill dam, an off-shore vertical breakwater built to protect an oil terminal, city buildings and a highway. We also stress that the current approach to the assessment of instability hazard can be transformed by capitalizing more on the presently underexploited advantage of the MTI technique, i.e., the capability to provide regularly spatially dense quantitative information for large areas where engineering infrastructure may currently be unaffected by instability, but where the terrain and infrastructure history (e.g., aging) may indicate potential for future failures.

In this research, univariate and bivariate statistical methods were applied to rainfall, river and piezometric level datasets belonging to 24-year time series (1986-2009). These methods, which often are used to understand the effects of precipitation on rivers and karstic springs discharge, have been used to assess piezometric level response to rainfall and river level fluctuations in a porous aquifer. A rain gauge, a river level gauge and three wells, located in Central Italy along the lower Pescara River valley in correspondence of its important alluvial aquifer, provided the data. Statistical analysis has been used within a known hydrogeological framework, which has been refined by mean of a photo-interpretation and a GPS survey. Water-groundwater relationships were identified following the autocorrelation and cross-correlation analyses. Spectral analysis and mono-fractal features of time series were assessed to provide information on multi-year variability, data distributions, their fractal dimension and the distribution return time within the historical time series. The statistical-mathematical results were interpreted through fieldwork that identified distinct groundwater flowpaths within the aquifer and enabled the implementation of a conceptual model, improving the knowledge on water resources management tools.
