Groundwater is the main water supply for agricultural and industrial needs in many coastal plains worldwide. Groundwater depletion often triggers land subsidence, which threatens manmade infrastructure and activities and aggravates other geohazards. We applied a multi-temporal interferometric synthetic aperture radar technique to Sentinel-1 datasets to detect ground motion in the Gioia Tauro plain (Calabria, Southern Italy) from 2018 to 2021. The InSAR data were analysed through the integrated use of groundwater head, stratigraphical and geomorphological data, and land use information to distinguish the potential subsidence divers. The results show that subsiding areas, with a mean rate of about 10 mm/yr, are in the middle of the plain, and their location is influenced by the spatial distribution of compressible sediments included in the shallow aquifer. Furthermore, the subsidence arrangement is spatially accordant with the main groundwater depression area, which can be ascribed to the ongoing and increasing water pumping for predominantly agricultural usage. We also observed that subsidence (up to 10 mm/yr) affects the western dock of the Gioia Tauro harbour, in front of which, in very shallow water, are two submarine canyon heads already affected by slides in the past.

Naples has always had a very special relationship with its underground layers_
under the 0 level, there is the negative face of the aboveground city; so far, not
entirely rediscovered, monitored, or valorized. Those spaces offer the key to a
deeper knowledge on the urban history of the city because, even though this
geological area is not characterized by natural caves at all, all Neapolitan artificial
cavities are a testimony to the life of the inhabitants and the skills they adopted to
maximize the potential of the profitable natural location of the city. Nowadays
monitoring underground networks is fundamental to guarantee the security of the
present aboveground city, but, at the same time, underground space can also be a
resource for future networking, in the respect of archeological layers. Underground
space can also be adopted in the definition of cultural routes and can
stimulate the creation of virtual tours as well. With such a multifaceted character,
a multidisciplinary approach to the underground layers of Naples is required. This
chapter is the result of a multidisciplinary approach to the study of Naples'
underground.

Apulia is an almost entirely karst region in southern Italy, being characterized by several thousand-meter-thick Mesozoic carbonate succession, diffusely outcropping in the Gargano (north), Murge (center) and Salento (south) areas.
It is surrounded by Adriatic and Ionian seas for most of its extent, with over 850 km of coasts and a significant, but not yet quantified, amount of freshwater gushing out along coastline or offshore. Mainly the coastal sectors of Apulian aquifers are then strongly exposed to seawater intrusion phenomena for both natural causes, due to the presence of fractures and karst forms, or human induced causes, such as sea level rise and over-exploitation.
Focusing on Murge area, the groundwater discharge to the sea typically occurs in a diffuse way, through groundwater fractures; locally it is concentrated where karst conduits reach the sea or coastal zones, that is where the hydraulic function of karst conduits for freshwater transfer prevails. Many thermal anomalies have been detected in the past thanks to multi-spectral aerial surveys (visible, infrared and thermal infrared), due to differences in temperatures between spring water and seawater.
In this work, we describe the Adriatic coast between the city of Monopoli and the Torre Canne place_ in this area, the main known springs show average discharges ranging from 300-400 to 600 l/s, with maximum peaks slightly lower than 1.200 l/s. This is the coastal stretch where most of the thermal anomalies have been recognized as submarine springs. In addition, at several other locations, in the immediate proximity and along the coasts, there are proofs of water emergencies. To provide a contribution aimed at improving the knowledge about hydrogeology of this sector of Murge, we present new data on the karst coastal springs and a first attempt to link them with those coming out from the main inland recharge area.

Abstract
The increasing use of groundwater and the effect of seawater intrusion makes the study of ...
The increasing use of groundwater and the effect of seawater intrusion makes the study of coastal aquifers extremely relevant. There are various measures, practices, and actions throughout the world for managing groundwater when this natural resource is subject to salinization risk. This research, focusing on the effect of seawater intrusion, classifies the different practical solutions protecting groundwater through salinization mitigation across the Mediterranean Area with a literature review. The literature review was based on the study of about 300 papers, which are mainly international journal articles (76%). The remaining papers include
conference papers (11.8%), reports and theses (7%), and books or chapters of a book (25%). Three main schematic groundwater management approaches can be distinguished for the use of groundwater resources at risk of salinization.
The engineering approaches optimize the quality and quantity of the discharged fresh groundwater. The most recent experiences of tapping submarine springs have been realized in the Mediterranean Sea using underground concrete dams, tools shaped like a parachute or tulip (including flexible tubes and a plexiglass dome), or a fiberglass telescopic tube-bell, especially in the case of karstic aquifers. The current widespread form of the engineering approach is to address the issue of groundwater exploitation by wells. More complex solutions use subhorizontal designs. These works include horizontal drains or radial tunnels bored inside the saturated aquifer, shafts excavated down to the sea level with radial galleries. These solutions have been successfully applied in Malta Islands. The discharge management approach encompasses at least an entire coastal aquifer and defines rules concerning groundwater utilisation and well discharge. A multi-methodological approach based on monitoring networks, spatiotemporal analysis of groundwater quality changes, and multiparameter well logging is described in Apulian karstic coastal aquifers (Italy). The core is the definition of the salinity threshold value between pure fresh groundwater and saline groundwater mixture. The water and land management approach should be applied on a regional scale. The main choice for this approach is pursuing water-saving measures and water demand adaptation. In Guyennon et al. 2017 a multiple-users and multipleresources-
Water Supply System model is implemented to evaluate the effectiveness of Increasing the Maximum Capacity of the surface reservoir and Managed Aquifer Recharge in the Puglia, a semi-arid region of South Italy characterized by a conspicuous water demand for irrigation.

The United Nations General Assembly of 2015 approved the 2030 Agenda for Sustainable Development, which is based on the 17 sustainable development objectives (SDGs, Sustainable Development Goals). These objectives were assumed as landmarks to define the route of the regional decision, orienteering the legislative activity and the regional planning to the global context. The described experience is focused on the objective 7, concerning the development of renewable energy sources.
The use of low enthalpy geothermal systems is part of a regional strategy for mitigating and adapting to climate change in Apulia. These systems allow reduction of energy consumption and emission by fossil fuels, offering the best thermal comfort, and lend itself to integration with other thermal renewable energy sources, using heat pumps. Many projects were developed as many geothermal systems are operating in Apulia, some of which can be classified as best practices, which deserve to be brought to the attention of the decision makers. At same time, as the diffuse realization of these systems calls for a systematic definition of optimal technical criteria, defined considering possible natural risks and potential negative effects.
The cooperation between the Apulian Regional Council and the CNR is part of an evidence-based legislation process and is focused on two main scopes. At global scale, the selection for sharing purposes of data and best practices at local, regional, national and international level, which are functional to progress related to the long-term implementation of the SDGs, was pursued. At detailed or regional scale, a research on optimal criteria to guide the approval of new geothermal system was realized. Effects of system installation and use, including underground temperature variations, are considered, assessing any kind of natural risks due to use of low enthalpy geothermal system.

The increasing groundwater exploitation and contamination risks due to the progressive population growth in coastal areas are emphasised in the case of carbonate coastal aquifers (CCAs), the peculiarities of which, especially in the Mediterranean basin, constitute a scientific matter of worldwide relevance.
The CCAs of the Adriatic and Ionian coasts not only ensure the socio-economic development of the populations but feed with their spring waters valuable wetland and coastal environments with relevant and highly positive effects on ecosystems. The groundwater resources of CCAs are highly vulnerable, especially if affected by karstic phenomena, to the quality and quantity degradation phenomena, not only for the increasing water demand and the decreasing recharge due to climate changes but also in relation to the sea level changes and the pollutant loads due to the contamination occurred in the whole hydrogeological basins.
The aim of this study is to offer a systematic and synoptic view, useful for knowledge, management and forecast purposes, contributing to assure enduring availability of high-quality groundwater, conciliating water demand satisfaction with the ecological needs of coastal Adriatic and Ionian environments in which the role of groundwater is very important. A geodatabase, collecting information for all carbonate aquifers present along the Adriatic and Ionian coast, have been created. At the core, there is a Geographic Information System, in which are placed the spatial information regarding the geology of aquifers, hydrogeological and geochemical features, together with specific information concerning groundwater use of CCAs. The added value of this database is the availability of a wide bibliography related to CCAs, together with a schematised summary of key information realised considering available information in the whole geodatabase.

The Gioia Tauro plain (GTP) is an industrialized and agricultural coastal area of about 500 km2in the Tyrrhenian side of Calabria. Its harbour is one of the most important container traffic hubs in the Mediterranean basin. The GTP groundwater resources are constantly at risk of depletion and quality degradation due to anthropic activities.
GTP is a half-graben bounded by two massifs. The boundaries are marked by three main fault systems_ the Nicotera-Gioiosa fault zone, NW-SE striking and right lateral kinematics along the north boundary; the NNE-SSW Cittanova Fault, a high-angle normal and active fault along the eastern border; the Palmi-Locri fault zone with NW-SE trend and a mainly strike-slip kinematics along the south boundary. The GTP sedimentary infill is made by an upper Miocene siliciclastic and carbonate succession overlays by Pliocene marly-limestone rhytmites and Piacenzian-Calabrian sandstones and calcarenites with interbedded 20m thick volcaniclastic deposits. Upward, the sedimentary infill continues with alluvial (in eastern and middle sector) and coastal (in the western sector) deposits.
Six geochemical facies of groundwater were distinguished, with different salinities and temperatures (Italiano et al., 2010). The majority of samples is of cold shallow groundwater and shows Ca-HCO3, Ca(Mg-Na)-HCO3(Cl-SO4) and Na-HCO3composition and overall low salinities (TDS <1g / L). Only few samples, with Na-SO4and Na-Cl composition, show high salinity (TDS <3.5g / L) and temperature (above 20 ° C). These latter occur in the northern portion of the plain, near the intersection of the Palmi-Gioia Tauro and Nicotera-Gioiosa faults systems, and in the southern sector, near Palmi town.
It was created a geodatabase using data of hundreds of boreholes, geotechnical and geophysical investigations. Furthermore, it is carrying out a geological and geophysical survey along the plain boundaries using passive seismic technique to infer the deep of discontinuities among the main geological units described above. The acquired data allowed to identify_ i) the shallow aquifer, made by Pleistocene-Holocene deposits characterized by complex lateral variations; ii) at the bottom, the aquitard, represented by Pliocene marls; iii) the deep aquifer, consisting of the upper Miocene succession. The highest thickness of shallow aquifer (more than 200 m) is observed in the
middle GTP sector. The thickness variation is strictly related to the NE-SW high angle normal faults which cross the GTP. The ongoing geological, geochemical, and geophysical surveys will allow_ i) to identify the geometry of the hydrogeological units; ii) to define the hydrogeological features of the groundwater systems useful for modelling purposes, and iii) to improve the knowledge of water rock interactions processes (e.g., relations between deep and shallow waters, anthropogenic effects, seawater intrusion) for management purposes.

In this study, we analysed the Gioia Tauro Plain (Tyrrhenian coast, southern Italy) in
terms of hydrostratigraphy and the physicochemical status of groundwater. We investigated the
hydrostratigraphic framework of the area identifying a deep aquifer (made by late Miocene succession), an aquitard (consisting of Pliocene clayey and silty deposits) and a shallow aquifer (including
Late Pleistocene and Holocene marine and alluvial sediments) using subsoil data (boreholes and
geophysics). Our reconstruction showed that the structural geology controls the spatial pattern
of the aquitard top and the shallow aquifer thickness. Furthermore, we evaluated the hydraulic
conductivity for the shallow aquifer using an empirical method, calibrated by slug tests, obtaining
values ranging from 10-4
to 10-5 m/s with a maximum of 10-3 m/s located close to inland dune
fields. The piezometric level of the shallow aquifer recorded a significant drop between the 1970s
and 2021 (-35 m as the worst value). It is the effect of climate and soil use changes, the latter being
the increased water demand for kiwi cultivation. Despite the overexploitation of the shallow aquifer,
shallow groundwater is fresh (736 µS/cm as mean electrical conductivity) except for a narrow coastal
area where the electrical conductivity is more than 1500 µS/cm, which can be due to the seawater
intrusion. What was more complex was the physicochemical status of the deep aquifer characterised
by high temperature (up to 25.8 oC) and electrical conductivity up to 10,520 µS/cm along the northern
and southern plain boundaries marked by tectonic structures. This issue suggested the dominant role
of the local fault system that is likely affecting the deep groundwater flow and its chemical evolution.

The increasing groundwater exploitation and contamination risks due to the progressive population growth in coastal areas are emphasized in the case of carbonate coastal aquifers, the peculiarities of which, especially in the Mediterranean basin, constitute a scientific matter of worldwide relevance, especially as some of these are wide transboundary aquifers. These aquifers not only ensure the socio-economic development of the populations but feeds with their spring waters valuable wetland and coastal environments with relevant and highly positive effects on ecosystems. Their groundwater resources are highly vulnerable, especially if affected by karstic phenomena, to the quality and quantity degradation phenomena, not only for the increasing water demand and the decreasing recharge due to climate changes but also in relation to the sea level changes and the pollutant loads due to the contamination occurred in the whole hydrogeological basins.

The added value of this database is the availability of a wide bibliography related to CCAs, together with a schematized summary of key information realized considering available information in the whole geodatabase. This study meets the requirements connected with UN Sustainable Development Goals, SDG 6 - Environment (Ensure availability and sustainable management of water and sanitation for all). Basing on this broad approach, the conceptualization and the management of any transboundary aquifer could be planned, starting from the information sharing. The potentialities of the knowledge system are shown for selected study case, e.g. transboundary aquifers between Croatia, Slovenia, and Italy.

Temperature is a key parameter in controlling the in-situ petrophysical properties, the solid and fluid phase equilibria, the stress-strain
relationships as well as the occurrence and potential of geothermal resources. Thermal field anomalies are determined by a great
number of different factors and the study of their nature together with a quantitative appraisal are critical in mapping the spatial
distribution of the conventional and unconventional geothermal resources as well as estimating the deep crustal conditions and their
lateral variability. With the aim to study the thermal structure of the upper crustal levels in Central-Southern Italy, we exploited
lithostratigraphic, hydrological, petrophysical and geophysical data. We described the main heat transport phenomena occurring in
the upper crust and we applied these concepts to a numerical modelling approach. We developed a new 3D geological model
considering the main lithothermal units acting as the cap-rock of the deep-seated hydrothermal systems, the regional carbonate
reservoirs and the crystalline/metamorphic basement. The temperature data from the accessible deep boreholes represented the main
thermal constraints of the models. The maximum logged depth is about 7 km, although the majority of the data distributes in the
depth range 1.5-3.5 km. At greater depths, seismological and rheological evidence (i.e. the thickness of the seismogenic layer) gave
us further indirect information regarding the deep thermal state of the upper crust. Along the Apennine chain, particularly in
correspondence of outcropping carbonate units, the temperature distribution is affected by downward heat advection. The most
favourable geological conditions leading to the development of high temperature hydrothermal systems occur far from the
outcropping carbonate units; especially in the Tyrrhenian side of the peninsula affected by crustal stretching and Plio-Pleistocene
magmatic activity.

In the Metaponto coastal plain (Basilicata region, southern Italy), the anthropogenic impact, mainly linked to agriculture and tourism, has significantly modified the land use and threatened the groundwater quality over the last century. Five protected sites located near the river mouths are included in the Natura 2000 network thanks to the high ecological value of their flora and fauna. The reduction of the groundwater flow, probably caused by the construction of dams and reservoirs for water storage, threatens the equilibrium of the coastal vegetated areas. Among the effects of groundwater quality modifications, the risk of salinity increase should be considered relevant.
The purpose of this paper is to describe the approach, which is preliminary to the density-driven flow modeling, supporting the implementation of management criteria facing seawater intrusion, climate change, and water demand in future scenarios. The definition of an accurate physically-based model is based on the geological and hydrogeological conceptualization and hydrochemical discussion.

In November 2016, an extreme rainfall event affected the Ligurian Alps (NW Italy). Consequently, several landslides and debris flows occurred in the upper Tanarello stream basin. In particular, the village of Monesi di Mendatica was severely damaged by two landslide phenomena_ the activation of a rotational landslide, which caused the total collapse of two buildings and part of the main road, and the reactivation of a deep-seated planar massive and a complex landslide, which widely fractured most of the buildings in the village. The latter phenomenon was mostly unknown and had never been monitored prior to the 2016 event. Due to the extensive damage, the village of Monesi was completely evacuated, and the road connecting a ski resort area in the upper part of the valley was closed. Furthermore, a potentially dangerous situation related to the eventual progressive evolution of this landslide that could cause a temporary occlusion of the Tanarello stream still remains. For this reason, we defined the landslide behaviour, triggering conditions and chronological evolution leading to the 2016 event using a multidisciplinary approach. This approach consisted of field surveys, satellite DInSAR time series analyses, digital image correlation techniques, rainfall records analyses, postevent monitoring campaigns and subsurface investigation data analyses, and numerical modelling. This multidisciplinary approach enhanced our understanding of this landslide, which is fundamental to better comprehend its behaviour and possible evolution.

The Metaponto coastal plain extends about 40 km along the Ionian coast, between the Sinni and Bradano Rivers (southern Italy). During the 20th century, the increases in modern irrigation systems, land reclamation works, the overexploitation of wells, and agricultural and industrial activities have deeply modified land use and groundwater availability and quality along the plain. These modifications negatively impacted the natural systems in terms of groundwater and soil salinization, magnifying the risks due to seawater intrusion. In this study, we explored the proneness to seawater intrusion, testing a multidisciplinary approach based on hydrochemical and geophysical investigations. A significant portion of the coastal plain was selected for this purpose. A set of 49 groundwater samples was analyzed to define the chemical characteristics of the water and geoelectrical measurements were recorded along three long profiles. The geoelectrical surveys showed in detail the aquifer bottom pattern where it is deeply incised by paleovalleys, defining the main hydrostratigraphic features, as it is necessary to prevent seawater intrusion worsening. The hydrochemical data highlighted areas with higher seawater intrusion proneness. The acquired measurements show the high proneness to seawater intrusion, especially where the aquifer bottom is very deep below the sea level, also far from the coast, and the relevance of the detailed knowledge of the aquifer bottom in supporting any kind of management.

Large earthquake-triggered landslides, in particular rock avalanches, can have catastrophic consequences. However, without accelerometer records, the recognition of slopes prone to such failures remains difficult, because slope-specific seismic response depends on many factors including local topography, landforms, structure and internal geology. We address these issues by exploring the case of a rock avalanche of >3 million m3 triggered by the 2008 Mw7.9 Wenchuan earthquake in the Longmen Shan range, China. The failure, denominated Yangjia gully rock avalanche, occurred in Beichuan County (Sichuan Province), one of the areas that suffered the highest shaking intensity and death toll caused by co-seismic landsliding. Even though the Wenchuan earthquake produced tens of large (volume > 1 million m3) rock avalanches, many of which resulted in dangerous landslides, few studies so far have examined the pre-2008 history of the failed slope or reported on the stratigraphic record of mass-movement deposits exposed along local river courses. The presented case of the Yangjia gully rock avalanche shows the importance of such attempts as they provide information on the recurrence of large slope failures and their associated hazards. Our effort stems from recognition, on 2005 satellite imagery, of topography and morphology indicative of a large, apparently pre-historic slope failure and the associated breached landslide dam, both features closely resembling the forms generated in the catastrophic 2008 earthquake. The follow-up reconstruction recognizes an earlier landslide deposit exhumed from beneath the 2008 Yangjia gully rock avalanche by fluvial erosion since May 2008. We infer a seismic trigger also for the pre-2008 rock avalanche based on the following circumstantial evidence_ i) the same source area (valley-facing, terminal portion of a flat-topped, elongated mountain ridge) located within one and a half kilometer of the seismically active Beichuan fault; ii) significant directional amplification of ground vibration, sub-parallel to the failed slope direction, detected via ambient noise measurements on the ridge adjacent to the source area of the 2008 rock avalanche and iii) common depositional and textural features of the two landslide deposits. Then, we show how, through consideration of the broader geomorphic and seismo-tectonic contexts, one can gain insight into the spatial and temporal recurrence of catastrophic slope failures in Beichuan County and elsewhere in the Longmen Shan. This insight, combined with local-scale geologic and geomorphologic knowledge, may guide selection of suspect slopes for reconnaissance, wide-area ambient noise investigation aimed at discriminating their relative susceptibility to co-seismic catastrophic failures. We indicate the feasibility of such investigations through the example of this study, which uses 3-component velocimeters designed to register low amplitude ground vibration.

The use of geothermal energy resources to support anthropogenic activities have a long-lasting tradition, renewed in recent decades with the increasing use of low enthalpy geothermal energy (LEG) with combined systems of heat pumps and geothermal exchange, exploiting the enormous thermal capacity and very low temperature variability of subsoil, including rocks and water. The further potential global increase of LEG use could be enormous, although LEG is already the main geothermal energy sources in Europe, contributing significantly to reach 2030 UN sustainable development goals (SDGs) on renewable energy resources, as a further leg to support all necessary efforts for these scopes. This research pursues LEG spreading improving knowledge on limitations of guidelines, technical regulations and/or laws, briefly rules, especially in terms of potential risks or limitations due to environmental constrains or natural phenomena. A global documentary research, including scientific articles, books, technical reports from qualified institutions, technical standards, guidelines, regulations, and laws, was realized with three different groups of keywords. A total of 161 documents were selected after some steps, including quality check. Identical English and Italian keyword sets were used to span from an international global scale to the complex local scale which characterizes the Italian experience. A complex sheet was filled in for each document, supporting data discussion, planned with a geographical criterion, from global to local. The system of rules resulted worldwide inhomogeneous and complex, with high differences from countries, nations or regions, also at local scale. The low quality or the absence of simple and careful "rules" emerged an important obstacle to LEG diffusion that can guarantee sustainability and the absence of natural risks. Main virtuous systems of rules were recognized as very useful to promote LEG spreading but these are still uncommon. The discussion of optimal experiences and the overview of potential natural risks due to LEG complete the paper.

Gli studi relativi alle procedure metodologiche per la valutazione delle instabilità costiere nel primo semestre 2020 purtroppo sono stati rallentati a causa della chiusura dovuta alla emergenza COVID 19, soprattutto per quanto riguarda sopralluoghi, verifiche e controlli in situ, e comunque sono continuati gli scambi di opinioni e le discussioni tramite riunioni online con tutti i partecipanti al WP8. E' stato avviato uno studio sul moto ondoso e sulle caratteristiche delle onde durante le forti mareggiate. I dati consultati, provenienti dal database RON (Rete Ondametrica Nazionale), comprendono il periodo Gennaio 2010 - Dicembre 2014. Le variabili coinvolte e considerate sono diverse e comprendono_ a) l'altezza d'onda; b) come l'energia delle onde viene modificata dal fondale prima di raggiungere la costa, quindi dalla presenza o meno della piattaforma di abrasione; c) la direzione di incidenza del moto ondoso rispetto alla linea di costa.
La direzione della maggior parte delle mareggiate segue quella dei venti predominanti e cioè E-SE e N-NE.

Nel presente articolo, dopo aver individuato le tipologie di costa più frequenti nella Regione pugliese vengono analizzati i meccanismi e le cause della diffusa instabilità delle coste rocciose alte. Questa problematica riveste carattere di enorme rilevanza regionale anche tenuto conto dell'estensione delle coste alte potenzialmente interessate a questo fenomeno. La morfodinamica costiera determina nel tempo una variazione dei versanti e delle falesie. L'evoluzione della costa alta può essere, in alcuni casi continua e lenta, in altri discontinua e veloce, a seconda delle azioni dirette e indirette compiute dagli agenti esterni sul litorale.
I dissesti possono essere episodici e discontinui nel tempo e nello spazio. Le falesie pugliesi sono intagliate in rocce carbonatiche mesozoiche stratificate e fessurate e calcareniti plio-pleistoceniche. I dissesti più diffusi sono riferibili a crolli di blocchi o di porzioni di ammasso roccioso, ribaltamenti, scivolamenti planari o rotazionali e scivolamenti di cunei.
Il moto ondoso rappresenta la principale causa di dissesto delle pareti rocciose e insieme con le correnti marine e maree, costituisce il più importante agente morfogenetico delle coste alte, insieme al weathering e ai processi erosivi molto attivi sulle facies calcarenitiche. I fattori che controllano i processi morfodinamici costieri sono rappresentati da fenomeni di_ 1) lungo e medio termine_ variazioni relative del livello marino, eustatismo, tettonica, effetti locali; 2) i processi continui sono le azioni di deposizione/erosione del moto ondoso, correnti, maree, trasporto dei sedimenti lungo costa; 3) di breve termine_ eventi parossistici e/o improvvisi dovuti a grandi mareggiate, tsunami, alluvioni, crolli istantanei. Non ultima vi è l'azione antropica, lenta ma continua.
Ai fini della valutazione della pericolosità è di primaria importanza il monitoraggio dell'evoluzione di alcune situazioni particolarmente critiche anche per la definizione di possibili interventi di mitigazione.

Groundwater salinization caused by natural and anthropogenic processes can increase the salinity above the concentrations ...
Groundwater salinization caused by natural and anthropogenic processes can increase the salinity above the concentrations recommended for specific uses or environments. Approximately 16% of the total land area on Earth suffers from groundwater salinization, potentially creating significant social, economic, and environmental problems. Global bibliographical research focusing on studies related to the utilization and management of salinization-threatened groundwater was conducted. A database of 520 papers from 85 countries was compiled and discussed. The main salinization sources were identified, and seawater intrusion is the primary studied phenomenon. This paper classifies different state-of-the-art approaches for protecting groundwater resources from salinization. Practical scientific solutions, from technical and engineering solutions to rules or regulatory instruments, are discussed from a global perspective. As salinization risk becomes a relevant problem, more complex initiatives should be applied to meet water demands while minimizing disadvantages. From the lowest to the highest complexity, three approaches were defined_ the engineering approach, the discharge management approach, and the water and land management approach. The discussion presents directions for future research opportunities.

The deepest cave in Apulia, an almost entirely karst
region in southeastern Italy, has recently been the object
of a project aimed at evaluating the quality and quantity
of the groundwater resources. The cave system, located in
one of the most remarkable karst landforms in the region
(Canale di Pirro polje), reaches the water table at a depth
of -264 m. Diving explorations brought the total depth of
the cave down to -324 m. This contribution illustrates the
preliminary activities carried out during the project, with
a particular focus on geology, morphology and structural
geology of the cave system and surrounding areas,
together with hydrogeological research and chemical
analyses of the groundwater.

Il lavoro descrive le carte inventario delle frane, di tipo geomorfologico e multi-temporale, preparate per una parte del territorio comunale di Motta Montecorvino, che ricade nel settore collinare e montuoso del Sub-Appennino Dauno (Provincia di Foggia, Puglia). Il lavoro è realizzato nell'ambito del progetto "Valutazione integrata dei fenomeni di instabilità geo-idrologica in Puglia, modelli interpretativi e definizione delle soglie di pioggia per l'innesco di frane" ed ha lo scopo di produrre una carta inventario delle frane di tipo geomorfologico per tutto il territorio Dauno e carte inventario di tipo multi-temporali per dieci centri abitati. La mappatura delle frane è realizzata attraverso l'interpretazione di più serie di fotografie aeree stereoscopiche in bianco e nero a diverse scale, per il periodo dal 1954 al 2003. La carta inventario geomorfologica di Motta Montecorvino, evidenzia un'elevata presenza di frane con dimensioni che vanno da centinaia di metri quadrati a qualche decina di ettari, mentre la carta inventario multi-temporale mostra un elevato numero di frane recenti di piccole-medie dimensioni, all'interno o in prossimità dei corpi di frane preesistenti e di maggiori dimensioni.

Geophysical investigations could provide a valid tool for the identification of possible causes of settlement phenomena that affect civil buildings. They provide a non-invasive method of obtaining high-resolution information about the subsoil, saving time and money. However, uncertainties related to the accurate interpretation of the acquired data could potentially reduce the value of these methods. For this reason, the integration of non-invasive tests with direct measurements to support geophysical data interpretation is strongly recommended. This is a fundamental step in the process of defining a sufficiently reliable geological model to explain the cause of failure. Among the various geophysical techniques, electrical resistivity tomography and ground penetrating radar offer significant advantages for monitoring the status of the conservation of civil engineering structures and infrastructures. This paper presents the most recent and beneficial advances of the use of electric and electromagnetic geophysical methods in the field of civil engineering, with particular attention to their applications for monitoring subsidence and settlement phenomena. Finally, the possibilities of the joint use of resistivity and electromagnetic methods for studying the causes of the structural decay that affects two precast buildings are monitored and discussed. The results demonstrate the capability of combining non-destructive geophysical techniques with direct data, for evaluating the safety of building constructions and solving geotechnical problems.

Gli studi relativi alle procedure metodologiche per la valutazione delle instabilità costiere nel secondo semestre 2019 sono continuati sull'analisi dei processi in corso. L'ultimo scorcio del 2019 è stato caratterizzato da ulteriori crolli lungo la costa salentina del Comune di Melendugno. Dall'osservazione del fenomeno si può notare come l'instabilità si è verificata a seguito di forti mareggiate, che allo stato attuale dello studio, sembra rappresentare il principale fattore di innesco dei crolli. Quindi, come già evidenziato nei precedenti reports il moto ondoso costituisce la più importante causa di dissesto delle pareti rocciose. Le variabili coinvolte sono diverse e comprendono_ a) l'altezza d'onda; b) come l'energia delle onde viene modificata dal fondale prima di raggiungere la costa; c) la dissipazione dell'energia d'onda infranta in prossimità della riva; d) la pressione dinamica delle onde alla base della scogliera; e) l'energia cinetica è dipendente dalla massa d'acqua, dalla sua velocità e dalla durata nel tempo. Tutto ciò produce forti vibrazioni nelle pareti calcarenitiche già indebolite dall'erosione subaerea.

Seismic site effects (local topographic/lithologic amplification, directivity phenomena) can have substantial impact on slope dynamic response and susceptibility to earthquake-induced failures. However, the instrumental data needed to quantify the site effects on slopes are still scarce. Here we investigate dynamic response of steep slopes in the Dadu River valley (Sichuan Province), one of the China's regions most struck by large magnitude earthquakes. We analyse ambient noise recordings acquired at the sites of a local accelerometer network established few years after the 2008 Wenchuan earthquake. The analysis benefits from the application of a new technique that determines the ellipticity of Rayleigh waves present in noise wavefield from the instantaneous polarization analysis of the recorded signals. The technique is adapted for application to steep surface by rotating the noise recordings according to a reference having as axes the slope down-dip direction, the slope surface strike and the normal to the slope surface. This allows obtaining the curve of Rayleigh wave ellipticity as function of frequency, whose maxima provide information on site response characteristics, and leads to a more reliable identification of resonance phenomena on steep slopes (40° inclination). The results of the ambient noise analysis are consistent with the available accelerometer data and provide clear indication of significant resonance effects, with regard to their potential impact on local seismic slope stability. In particular, the slopes around the confluence of a local torrent with the Dadu River near the Lengzhuguan village exhibit strong site amplifications related to the presence of surficial deposits overlying intensely fractured granite bedrock. The frequency, amplitude and direction of resonance phenomena derived from the analysis of instrumental data indicate that site amplification is likely to have lesser impact on the stability of the lower part of the Mt. Dagang, which forms a long steep sub-planar slope facing the Dadu River. Our findings demonstrate that expeditious ambient noise recordings can provide useful information on relative susceptibility of slopes to seismically induced failures.

The impoundment of the 660-km long reservoir behind the huge Three Gorges Dam, the world's largest hydropower station, increased regional seismicity and reactivated severe geohazards. Before the reservoir filling was initiated in 2003, the region had approximately two earthquakes per year with magnitudes between 3.0 and 4.9; after the full impoundment in 2008, approximately 14 earthquakes per year occurred with magnitudes between 3.0 and 5.4. In addition, hundreds of landslides were reactivated and are now in a state of intermittent creep. Many landslides exhibit step-like annual pattern of displacement in response to quasi-regular variations in seasonal rainfall and reservoir level. Additional problems include rock avalanches, impulse waves and debris flows. The seriousness of these events motivated numerous studies that resulted in 1) Better insight into the behavior and evolution mechanism of geohazards in the Three Gorges Reservoir Area (TGRA); 2) Implementation of monitoring and early-warning systems of geohazards; and 3) Design and construction of preventive countermeasures including lattice anchors, stabilizing piles, rock bolts, drainage canals and tunnels, and huge revetments. This paper reviews the hydro-geologic setting of TGRA geohazards, examines their occurrence and evolution in the past few decades, offers insight learned from extensive research on TGRA geohazards, and suggests topics for future research to address the remaining challenges.

Loess is a meta-stable, cemented assemblage of mainly silt and clay-sized particles of low plasticity. When dry it behaves like a brittle material, but when wetted up the fabric rapidly collapses. Unique geomorphological features include extensive surface erosion, soil piping (loess 'karst'), catastrophic landslides, and widespread collapse (hydro-consolidation). The Chinese Loess Plateau is a more or less continuous drape of thick loess covering some 440,000 km2. It is one of China's regions that is most prone to geohazards. This paper reviews advances in the research related to loess geohazards, drawing particular attention to the need to apply research findings to recent, very large (mega-)construction projects in loess terrain such as the Mountain Excavation and City Construction in Yan'an levelling 78 km2 for urban expansion, the Lanzhou New District creating 246 km2 of new level ground for construction, and large engineered interventions in the landscape for gully control and land reclamation such as those in Shaanxi and Gansu generating agricultural land covering an area of some 8000 km2. These projects are in response to increasing pressures to facilitate expansion of urban centres, their interconnecting infrastructures and their agricultural support systems. It is argued that, where proper application of scientific knowledge for engineering control (e.g. densification, drainage) of these new landscapes is absent, these projects could generate a substantial, and costly geohazard legacy for future generations.

Le tematiche trattate in questa giornata, estremamente importanti e attuali, sono relative al rischio costiero e sono indirizzate soprattutto all'erosione con conseguente arretramento dei litorali sabbiosi, comprendendo anche la subsidenza e alluvionamento delle piane costiere. Nell'ambito di tali problematiche vanno annoverati anche i fenomeni di instabilità che affliggono le coste rocciose, e questa breve chiacchierata è focalizzata ai crolli e alle frane costiere che mettono a rischio non solo la sicurezza delle persone ma sono anche una minaccia alla fruibilità dei luoghi. La vocazione turistica della nostra regione pone questa problematica tra quelle assolutamente prioritarie per la definizione della suscettibilità e della pericolosità da frana e della definizione del rischio per l'individuazione di interventi di mitigazione.
