Five sinkholes have recently been identified in the territory of San Basile (Northern Calabria, Southern Italy), in locality "Piano dell'Acqua". The sinkholes are located in a hilly setting, where the main landform is represented by a slight valley draining toward the east. The sinkholes are limited in size, with maximum diameter of 10 m, and maximum depth of 2.5 m. Two of them are elongated, whilst the remaining three are circular. The area where the sinkholes develop is characterized by Pliocene conglomerate and sand, likely dislocated by tectonic lines. The sinkholes were initially examined by means of multi-temporal aerial photos, and the outcomes from this analysis were checked in the field through geological, structural and geomorphological surveys. At the same time, an historical analysis was started in order to collect and critically evaluate the existing information and testimonies about age of occurrence of the phenomena. At this aim, several interviews with local inhabitants were performed, and a number of archives scrutinized. As a result, the study allowed to hypothesize that two sinkholes developed during the winter 2000-2001, with likely rapid formation. Two other cases probably originated during the 70's, as also suggested by the age of the vegetation hosted within the sinkholes. The last sinkhole, eventually, opened sometime between February 2001 and November 2007. According to the collected testimonies, a further phase of sinkhole development might have occurred in the first half of the past Century, but no field evidence of this older phase has been found so far. Analysis of the seismic catalogues showed that no earthquake can be identified as possible trigger of any of the sinkholes at Piano dell'Acqua. Therefore, the origin of the studied phenomena should be related to sub-cutaneous erosion, within an area that is rich in groundwater (as also shown by the site name, meaning "Water Plain"). Local changes in the water table, both related to climate and man-induced activities, may have triggered the development of the sinkholes that can be classified as belonging to the "suffusion" or "dropout" types (depending on whether the surface materials are made of, respectively, cohesive or not cohesive deposits).

Within the framework of a regional study, recently performed to implement a data base of the sinkholes in plain areas in Calabria, n.5 cases have been recognised in the territory of San Basile (Northern Calabria) at "Piano dell'Acqua". The sinkholes are located in a hilly setting, in which the main landform is a slight valley draining toward the east. The area is characterized by Pliocene conglomerate and sand, likely dislocated by tectonic lines. The sinkholes show a variable freshness appearance. They are limited in size, with maximum diameter of 10 m, and maximum depth of 2.5 m; two of them are elongated, whilst the remaining three are circular.

The PSI (Persistent Scatterer Interferometry) processing of ENVISAT ASAR data (period 2003-2010) provided spatially dense information (more than 400 PS/km2) on ground surface displacements in Lanzhou, capital of Gansu Province, NW China. The geomorphological and geological context of the local Yellow River valley indicate that the lower, flat areas with floodplain and valley-fill deposits (Holocene terraces with mainly reworked loess at the surface) are stable, whereas some higher, gently sloping valley sides appear locally unstable, particularly where the Late Pleistocene terraces are covered by young aeolian (Malan) loess. The PS velocity data suggest that the relative susceptibility to ground and slope instabilities is the highest on the 4th and 5th order river terraces. This is consistent with the presence of collapsible Malan loess and recent land use of these terraces involving irrigation and construction.

Understanding past sea-level change plays an important role in determining the underlying causes, and also allows the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. A compilation of global sea-level estimates based on deep-sea oxygen isotope ratios at millennial-scale resolution or higher was published since '70. These global sea level curves do not take in account isostasy and tectonics. Observed sea level change can be reconstructed from dated fossils, coral reef terraces, speleothems, emerged and forming terraces on coastal areas, archaeological and other markers well connected with sea level. Because of the lack of coral reefs in the Mediterranean sea, results on late Quaternary sea level changes have been difficult to obtain in comparison with typical sites such as Barbados, the Huon Peninsula, Tahiti, Florida and others. On the contrary the very low tidal range of Mediterranean seas offers a good opportunity to produce precise observations and considerations on climatic change.

Recurrence of damaging floods and role of population number in a karstic area (Bari, southern Italy)

M. Polemio, V. Dragone, 2012, Recurrence of damaging floods and role of population number in a karstic area (Bari, southern Italy), EGU Leonardo Topical Conference Series on the hydrological cycle 2012 - Hydrology and Society, pp. 65, Torino, Italy, 14/16 novembre 2012,

Abstract

In karstic areas cases floods are rare, short, and sudden but the effects are often very dramatic. Flash floods (local floods of great volume and short duration, defined by the USA National Weather Service as floods caused by heavy rainfall in a short period of time, generally less than 6 hours) are extremely dangerous. Recent years have seen several flood-related casualties in Italy, in 2003, 2005 (when the last catastrophic flood happened in the karstic area of Bari), and 2007. Flash flood warnings are intrinsically difficult due to the short time available to warn people living next to the river. Our goal in this study was to contribute to the understanding of the relationship between flood events in karstic areas, in terms of recurrence, exceptionality and/or intensity, anthropogenic effects, mainly in terms of population number variations, and damages. Some authors have shown that urbanisation, land use changes, and hydraulics works must be taken into account to really understand the effects of past flood events. A comparative analysis of these data can thus allow us to understand if the trend of flood damage is steady or increasing and to determine whether it is affected by the growing density of population and facilities in flood-prone areas.The approach was based on three types of analyses_ the historical analysis, based on historical data, the hydrological and the geomorphological analysis, both based on recent monitored or measured data. The historical analysis was focused on identifying and comparing two kinds of data_ the series of past flood events over a period sufficiently wide to define the flood recurrence period and the main steps of anthropogenic development, called the anthropogenic role. This role was expressed using the population number and needs and considering the facilities in flood-prone areas. The hydro-geomorphological analyses were based on two types of data. Long time series of the annual maximum rainfalls of short duration were used to assess the return period of high intensity rainfall that caused studied flood event(s) for which rainfall measurements were available. The geomorphological analysis considered rainfall, hydrogeological characteristics of outcropping rocks and soils, and geomorphological data on the drainage basin to calculate net rainfall and peak flow characteristics. The historical analysis of floods and damages highlighted four flood periods, distinguished on the basis of the recurrence period and the level of damages. The hydro-geomorphological analyses showed the peculiarities of the 2005 flood event. The maximum rainfall return period for the 2005 event was due to exceptional three-hour cumulative rainfall. The study case was a sub-catchment where very high rainfall intensities were observed. The rainfall return period was found to be roughly in the range of 50-100 years, considering a cumulative rainfall duration (3-hour) about equal to the concentration time. This study shows that main modifications of flood recurrence and level of damages can be justified considering the variation of population number.

Metodologie speditive per la valutazione del rischio di degrado quantitativo e qualitativo delle acque sotterranee della Puglia

La prevalente natura carsica del territorio limita la disponibilità di risorse idriche superficiali e conferisce valore particolare alle acque sotterranee della Puglia. Pregevoli per qualità, le acque sotterranee degli acquiferi pugliesi sono state prelevate in misura crescente a partire dai primi decenni del secolo scorso. La crescita dei prelievi ha sottoposto a notevoli "sollecitazioni" il sistema idrogeologico pugliese, dando concretezza ai rischi di degrado sia quantitativo sia qualitativo, rischi tra loro legati nel caso degli acquiferi costieri, quali sono quelli principali pugliesi. L'articolo descrive, con intenzionale brevità, i principali antefatti normativi che hanno regolamentato e regolamentano l'utilizzo delle acque sotterranee pugliesi, ponendo l'attenzione sugli obiettivi che occorre perseguire per coniugare il massimo soddisfacimento della domanda idrica con la duratura tutela di tali preziose risorse naturali e degli equilibri ecologici connessi. Per dare forza agli strumenti di gestione e di controllo e definire chiari obiettivi di tutela è necessario conoscere in modo quantitativo ed accurato quali siano i rischi reali. A questo fine si descrivono brevemente alcuni approcci metodologici accomunati dalla semplicità e dalla ripetibilità delle procedure in contesti non prioritariamente scientifici. L'articolo descrive la variazione della disponibilità della acque sotterranee pugliesi, fondamentalmente discutendo l'andamento dei trend piezometrici e delle portate delle sorgenti (minore attenzione è data al Gargano, per la scarsa disponibilità di dati, e al Tavoliere, per la minore qualità delle acque sotterranee). In sintesi, si osserva una tendenza alla riduzione della disponibilità spiccata ma, per fortuna, non monotona. Tale tendenza è solo in parte giustificabile in relazione alle modificazioni climatiche, che di certo hanno causato un calo della ricarica a partire dagli anni ottanta. Gli effetti più macroscopici riguardano la Murgia e il Tavoliere; rilevanti gli effetti in Salento, in particolare in relazione all'enfatizzazione dei rischi connessi all'intrusione marina. Per la valutazione dell'evoluzione del fenomeno dell'intrusione marina si descrive il criterio a soglia, che persegue l'individuazione del valore di soglia della salinità tra le acque sotterranee dolci e le acque sotterranee contenenti sia pure minime aliquote di acque saline di intrusione marina. Per le acque sotterranee degli acquiferi carbonatici pugliesi detta soglia è risultata pari a circa 0,5 g/l. A partire da tale soglia, si effettua un'analisi spazio-temporale, che permette di individuare le aree soggette a diversa vulnerabilità all'intrusione marina e di discriminare dove i rischi di degrado qualitativo sono più gravi. In ogni caso emerge la drammaticità degli effetti dell'intrusione marina nel Salento e la presenza di estese porzioni del territorio della Murgia e del Salento a rischio di degrado qualitativo per intrusione marina. L'articolo si conclude con alcune considerazioni sulla possibile implementazione delle conoscenze descritte in criteri di gestione delle acque sotterranee pugliesi.

The coastal carbonate Apulian aquifers, located in southern Italy, feed numerous coastal cold springs and constitute the main local source of high quality water. The group of Santa Cesarea springs constitutes the unique occurrence of thermal groundwater outflow, observed in partially submerged coastal caves. The spring water is rich of hydrogen sulfide; temperature ranges from 25 to 33 C°. For their properties, spring waters are used for spa activities from several decades. Hydrogeological spring conceptualisations proposed up now were not able to justify water geochemical peculiarities or were not completely confirmed up now. To reduce these uncertainties, a complex hydrogeological survey has been defined. Geological and structural surveys, chemical and isotopic groundwater analyses, spring and well discharge measurements, well loggings, multi-parameters spring automatized measurements, and cave explorations are ongoing. All available data have been used to improve the knowledge of groundwater flow system, including the valuable deep aquifer, the origin of the thermal waters, and to investigate the possibility of using low-enthalpy geothermal fluids to fulfil the thermal needs of the town of Santa Cesarea Terme.

Il contributo si basa sull'analisi di diversi tipi di dati, elaborati fino a costituire serie storiche mensili inerenti il clima (pioggia, temperatura, giorni piovosi e intensità di pioggia) dal 1877 al 2008. Nonostante la tendenza al calo della piovosità e dell'intensità di pioggia e all'incremento della temperatura e dei giorni piovosi, si osserva la crescente ricorrenza di piene e frane, a conferma della crescente antropizzazione di aree a pericolosità idrogeologica. La discussione delle relazioni clima-frane ha evidenziato delle limitazioni ragionevolmente dovute al concentrarsi delle frane in parte del territorio e alla minore qualità del dato storico.

Abstract
The coastal karst aquifers are known to be highly vulnerable to anthropogenic and natural changes, ...
The coastal karst aquifers are known to be highly vulnerable to anthropogenic and natural changes, and in particular to the overexploitation of groundwater resources. The high degree of vulnerability is due to their intrinsic characteristics, anthropogenic pollution, and the effects seawater intrusion. The progressive population concentration in coastal areas and the increasing discharge overlapped to peculiarities of karstic coastal aquifers constitute a huge worldwide problem, particularly relevant for coastal aquifers of the Mediterranean basin. In Italy, Apulia, with its coastline extending over 800 km, is the region with the largest coastal karst aquifers. The predominant karstic Apulian features make the region extremely poor of surface water resources and rich of high quality groundwater resources. These resources still allow the social and economic development of population, improving agricultural and tourist opportunities. The continuous increasing well discharge causes or contributes to the groundwater quality degradation, often making the groundwater unusable for irrigation and drinking (Polemio et al. 2009). The strategic importance of groundwater resources and its wise management for Apulian population is due to these risks (Cotecchia and Polemio 1998, Margiotta and Negri 2005). The aim of this study is to define the efficacy of existing management tools and to develop predictive scenarios to identify the best way to reconcile irrigation and drinking water demands with enduring availability of high quality groundwater. The Salento (Salentine Peninsula), was selected being the Apulian aquifer portion exposed to the highest risk of quality degradation due to seawater intrusion.

The availability of good quality water is worldwide a basic condition to pursue the socioeconomic development. The agriculture water demand can be damaged by contamination of groundwater resources. This paper proposes a tool to preserve the groundwater quality by using groundwater vulnerability assessment methods and a decision support system (DSS). Vulnerability map could be used for planning, policy, management, and contamination assessment. The mapping of intrinsic groundwater vulnerability was based on reliable methods, i.e., the DRASTIC and the SINTACS methods. A vulnerability map could be used for planning, policy, management, and contamination assessment. A DSS was developed in order to assess the groundwater vulnerability and pollution risk due to agricultural activities and land use changes. The proposed DSS software package was designed using the Matlab language. The software is a friendly application for everyone ranging from the novice user, e.g., a student, to an operations research scientist. It quickly and efficiently performs the task that is scheduled to carry out, and it can incorporate new maps in order to cover new areas. The tool was tested using two study areas located in the Mediterranean area. The test sites are dominated by different prevalent hydrogeological features, i.e., the typical porous features of alluvial deposits in the Greek study area and the typical fissured and karstic features of limestones and dolostones in the Italian study area.

This paper concerns the landslide process occurring on a cut slope in stiff clays located at the north of the town of Lucera in southern Italy. This unstable slope lies between a hospital at the top and an abandoned quarry at the toe_ the quarry was active until the end of the 1970s. A first landslide occurred around 1980, and was characterised by a subsequent retrogressive evolution. This paper presents an interpretation of the slope failure mechanism based on the results of geomorphological studies, field monitoring, laboratory testing, and both limit equilibrium and coupled numerical analyses, these latter carried out with FLAC2D. In particular, the numerical analyses have been performed in order to interpret the evolution of the slope movements with time, and to assess the influence of the quarrying-induced excess pore pressures on the development of the failure process. The numerical results show that during the excavation stages the negative excess pore water pressures due to undrained unloading allowed for a temporary stability of the slope. The analyses also indicate that the process of pore pressure equalisation triggered the 1980 failure, and initiated the retrogressive evolution of the landslide.

This presentation was based on the analysis of different types of data recorded to provide monthly time series related to climate (rainfall, wet days, rainfall intensity and temperature) from 1877 to 2008, in order to verify the relationship between climate changes and landslide occurrence in Apulia region. Despite the decreasing trend of rainfall and rainfall intensity and the increasing trend of temperatures and wet days, there is an increasing trend of landslide occurrence, highlighting the negative effect of anthropogenic activities in landslide-prone areas.

Climate variability and landslide occurrence in Apulia (Southern Italy)

Recent international researches have underlined the evidences of climate changes throughout the world such as the rise of temperature and the variation of distribution and intensity of rainfall. The aim of this paper is to verify if there are relations between climate changes and the occurrence of hydrogeological damaging events, especially landslides, in Apulia. The Apulia region is partially a peninsula located in southern Italy and has an area of 20.000 km2. Most of the region is flat, the few areas with relief are concentrated in the Subappennino dauno and Gargano (maximum altitude 1,152 m asl). In the region it can be distinguished three different geological domains_ foreland, foredeep and the Apennine mountain chain. The foreland is made of cretaceous limestones and it is represented by Salento, Murge and Gargano; the foredeep (Fossa Bradanica) is made of carbonate sediments settled during Plio-pleistocene, while Apennine thrust-belt is made of a series of terrigenous and marine deposits which settled in different basins that were stacked during the orogenic phase. At present these sediments are chaotic and present poor geotechnical characteristics. Both climate and landslide data have been obtained from available databases that have been expanded by authors. Climate data covers a period from 1877 to 2008; time series from 60 rain gauges of which 47 are thermometric were selected. The climate database collects data about monthly temperature, rainfall and wet days, where a wet day is defined as a day in which precipitation is equal or more than 1 mm. A complex statistical treatment was done to correct the anomaly in the data before 1920, which consider as a wet day every day with any amount of precipitation. Climate indices related to temperature, rainfall, wet days and rainfall intensity (as the ratio rainfall/wet days) have been calculated for each month and for the hydrological year (from September to August of the year after), to obtain only a set of data for the whole region. Landslide data came from historical archives and newspapers and it covers a period from 1918 to 2006. In Apulia 237 landslide events were observed; landslide data were organised on the basis of municipal monthly time series. Monthly and annual indices concerning climate and landslide occurrence were defined and calculated. During the mean hydrological year the maximum number of landslides occur in January; between December and February there is the 61% of total. January 2003 was the month with the highest number of landslide events (61 events in the Subappennino dauno). The trend analysis shows an increasing trend for landslides, despite the decreasing trend of rainfall and rainfall intensity and an increasing trend of temperature and wet days, climate favourable conditions to the reduction of landslide occurrence. These effects were justified highlighting the inappropriate land use in landslide prone areas. The regional landslide distribution is not homogeneous_ they are mainly concentrated on the Subappennino dauno, where the geological, morphological and geotechnical features are particularly favourable to landsliding. A more detailed analysis of climate and landslide occurrence data was conducted focusing on this regional zone.

Punishment for the Sinner_ Holocene episodic subsidence and steady tectonic motion at ancient Sybaris (Calabria, Southern Italy)

Although the Calabria region in southern Italy experienced Quaternary uplift, intense Holocene subsidence is documented at ancient Sybaris, one of the most powerful among the Greek colonies collectively known as Magna Greacia. Sybaris flourished along the Ionian Sea coast of north-eastern Calabria since 2.7 ka BP and until the end of the Roman empire, when it went progressively concealed below the ground. Study of the Latest PleistoceneeHolocene evolution of this area involved analysis of the relative sea-level history for individual borehole logs, based on re-calibration of published ages and stipulation of nominal sea-level positions related to each marker. For investigation of the short-term evolution, a novel compilation of geological and archaeological sea-level markers was supported by new radiometric ages. Appraisal of the position of dated markers, when compared to a sea-level curve built on purpose for this coast using an updated glacio-hydro-isostatic model, indicates a locally intense difference in vertical motion between boreholes located away from, or close to, the ancient town. Specifically, whereas data from the basement of the archaeological layers document large subsidence, more distant sites behaved differently. A site w2 km to the NW of the settlement was apparently stable throughout the Holocene, and a site w6 km to the SE experienced uplift at w1.5mm/y since 0.6 ka BP. In addition, analysis reveals temporal changes in subsidence pattern in the archaeological area. Large (5e6 mm/y) Early Holocene subsidence at Sybaris slowed to w1.5mm/y during the middle part of the Holocene. The slowing-down trend continued during and after historical occupation at w0.8 mm/y, a value similar to the long-term (35e40 ka BP) rate established from the deepest borehole samples. These data are interpreted as suggesting that sediment compaction affected the basement of Sybaris during the Early Holocene, and progressively ceased during historical times, when a tectonic signal prevailed. During historical time, the spatial difference in vertical motion is chiefly attributed to differential growth of nearby folds documented by morpho-tectonic studies on-land and seismic profiles analysis in the offshore of Sybaris. Whereas location above a syncline caused tectonic subsidence at Sybaris, the regions to the north and south record stability or uplift that reflects transition to growing anticlines. In the short term (1e10 ka scale), these local tectonic processes prevail over the regional uplift pattern, which is expressed at the 100 ka scale or over.
