Abstract: Heavy rains are very often responsible thr extensive mass movements. It has been the aim of this work to highlight the existence and intensity of the influence exerted by such rains in triggering selected landslides in Southern Italy, with reference to their main geomorphological features. Simple hydrological/statistical methods are suggested to predict landslide hazard caused by heavy rains.

C.; Montenegro, S. M. G. L. Abstract: 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.

P.; CNR-IRPI, Italy; Zuffiano', L. E.; CNR-IRPI, Italy; Santaloia, F.; CNR-IRPI, Italy Editors: Silva Jr., G. C.; Montenegro, S. M. G. L. Abstract: 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.

Abstract: A study of scale effects and gravity reveals that the relative scale of life would vary in different gravities. The large relative scale of ancient life indicates that ancient gravity was weaker and this has implications for the Expanding Earth theory.

Each type of phenomenon developing during DHEs is characterized by a proper dynamic and, according to the social and economical framework in which develops, it can cause different impacts on people and properties. Despite during storms all these phenomena occur at the same time (or in a short while), often amplifying damage and hinting emergency management, studies available in literature tend to analyze each type of phenomenon separately, supplying a fragmentary framework of either causes (rainfall) and effects (damage). A database concerning DHEs occurred in Calabria (southern Italy) since 1800 has been recently updated, by continuing a historical research which has been started since 2000. Basing on this huge amount of data (more than 10,000 records), an analysis of the series of DHEs occurred in a selected area/period is carried out. Both the methodological framework for DHEs analysis, based on damage classification and a classification of different DHEs types are presented.

T.; Lebbe, L.; Cruz, J.V.; Coutinho, R.; Langevin, C.; Buxo, A. Abstract: The quality of groundwater of Apulian carbonate aquifers is severely affected by salt quality degradation due to seawater intrusion which reduces the availability of high quality groundwater. To reduce these risks, some regional regulations were defined from seventies with the purpose to control the number of wells, the location and the authorised well discharge. The practical effects of these management criteria, the temporal and spatial trend of recharge, groundwater quality and seawater intrusion effects are discussed. Proposals for new management criteria are defined.

In particolare, viene caratterizzato il complesso di relazioni esistenti tra i corpi idrici superficiali e sotterranei in un'area che si estende per oltre 20 Km lungo la costa e per 6 Km verso l'interno. In tale area affiorano estesamente, costituendo l'acquifero per la falda idrica in studio, depositi detritici, sia marini che continentali, di natura ciottolosa, sabbiosa e argillosa. L'ambiente in cui si muovono le acque sotterranee in studio è condizionato dalla modesta soggiacenza della stessa, dalle profonde incisioni fluviali con foce sullo Ionio e dai relativi deflussi idrici, dall'infiltrazione naturale e non, dovuta quest'ultima all'intensa irrigazione, dagli afflussi provenienti da altri corpi idrici sotterranei, dalla presenza del mare nonchè dall'uso intenso nei mesi estivi della risorsa idrica sotterranea esaminata. Per caratterizzare il regime della falda in tali complesse condizioni sono stati raccolte numerose serie di dati idrologiche. I dati pluviometrici e termometrici, relativi a un periodo di tempo pari a oltre 60 anni, hanno permesso di caratterizzare il clima e studiare l'infiltazione. I dati idrometrici, disponibili per circa 40 anni, hanno permesso di caratterizzare il regime fluviale dei principali corsi idrici. La raccolta, infine, di dati piezometrici relativi a una rete attiva per circa 30 anni ha permesso di perseguire le finalità di studio che il lavoro illustra. Alcune metodologie statistiche sono state applicate al fine di caratterizzare il regime della falda e per evidenziare l'influenza che su di essa hanno i corpi idrici superficiali e l'azione dell'uomo. Lo studio ha considerato l'evoluzione temporale dei fenomeni, utilizzando anche l'analisi spettrale e di correlazione, nonchè spaziale, mediante approcci tipici della Geostatistica.

Universiteti Politeknik Tirane Editors: Ciani, A.; Università di Perugia Abstract: Water is a vital and precious resource for people and for ecosystems. We should make each possible effort to protect water resources and increase people’s access to clean and sufficient water. To pursue these purposes many efforts have been realised in terms of technical rules and national laws. This contribution describes the approach of the European Union, Italy and Albania, considering also some local government initiatives concerning the protection of water resources, in terms of availability and quality, and of ecosystems. Attention is given also to the effect of the whole water cycle management in terms of environmental protection and reduction of water-related natural disaster.
