Surface and subsurface environmental degradation in the karst of Apulia (southern Italy)

Karst environments are highly vulnerable to a variety of degradation and pollution problems. Geology (fractured carbonate rocks), morphology (presence of a network of cavities produced by karst processes), and hydrogeology (rapid concentrated flow through fractures and conduits) of karst carbonates strongly favour the movement of contaminants toward the water table. In particular, poor quality of subsurface water can derive from polluting substances flowing at the surface, and/or by direct immission of liquid and solid waste in the water table through the systems of conduits and joints in the rock mass. As a consequence, water quality can be severely deteriorated, which implies very high economic and social costs in order to clean the polluted sites and restore the original situation. In some cases, such as when the original karst morphology is changed because of anthropogenic interventions, the variations created in the landscape are not recoverable, and a loss of sites of naturalistic interest has to be registered. High vulnerability of a typical karst region of the Mediterranean area is illustrated in this paper by describing some case studies from Apulia, southern Italy. The Apulia region, where karst processes have had a prominent role in the development of the present landscape, is mostly underlain by intensely karstified limestones. Two cases of pollution due to solid waste into karst cavities (Grave di S. Leonardo in the Gargano Promontory, and Grave Pelosello in the Murge plateau), landscape transformation in the Minervino Murge area, and degradation of Gravina Monsignore, a typical karst valley in south-eastern Murge, are described in the paper. In two out of four cases, degradation of the sites was discovered thanks to activity from local speleologists, which also acted as promoters for cleaning and safeguarding the polluted sites. These examples underline well the mismanagement of karst territories (in particular, the common practice to dump refuse into sinkhole and caves), the pollution of limestone aquifers, and the effects that such pollution in karst areas might have in terms of risk to the public health.

The need of effective strategies for the prevention and mitigation of damage caused by earthquake-induced landslides has stimulated recent developments of techniques for the assessment of seismic landslide exposure at regional scale. However, for a rational risk management, a crucial element is represented by the “time horizon” of the hazardous events. A new way to incorporate the time factor in seismic landslide hazard assessment is proposed here. It consists in evaluating the temporal recurrence of seismically-induced slope failure conditions inferred from the Newmark’s model_ first, by adopting Arias Intensity to quantify seismic shaking, well established methods of seismic hazard assessment are employed to obtain the occurrence probabilities of different levels of seismic shaking in a time interval of interest; then, some empirical relations, based on the Newmark’s model, are employed to evaluate the slope critical acceleration ac for which a pre-fixed probability exists that seismic shaking would result in landslide triggering. The obtained ac values represent the minimum slope resistance required to keep the probability of seismic landslide triggering within the pre-fixed value. Therefore, the space distribution of the calculated ac values can be promptly compared with the actual in-situ ac values of specific slopes in order to estimate whether these slopes have a significant probability to fail under seismic action in the future. An example of this approach, applied to an area of the Southern Italy (Daunia region), shows that the introduction of the time factor modifies significantly the representation of spatial hazard and allows to evaluate the relevance of seismicity as landslide triggering agent.

This paper deals with a Southern Italy area, 40 km by 10 km wide, located where four river valleys anastomose themselves in the coastal plain. The geological and hydrogeological features of the study area and the chemical-physical groundwater characterisation have been inferred from the data analysis of 1130 boreholes. Some aquifers, connected among them, constituted by soils of different geological origin -marine terraces deposits, river valley alluvial deposits and alluvial and coastal deposits - have been considered. The coastal plain aquifer is the most interesting for practical utilisation. Groundwater flow is mainly unconfined in the marine terraces and in the river valleys while it becomes mostly confined in the coastal plain aquifer. An upper clayey layer overlies the sandy coastal aquifer characterised by a mean hydraulic conductivity value equal to 2.3 10-4 m/s. The bottom is a silty-clayey bed which lies under the sea level. Being the direct natural recharge extremely low, the recharge of this coastal aquifer is mainly guaranteed by the discharge from upward aquifers and from the river leakage. The new acquired knowledge permits to delineate scenarios useful for an optimization of the groundwater resources tapping and for pursuing the safeguard of them. Resumen.

Si descrivono le metodologie utilizzate e i risultati conseguiti con uno studio di dettaglio di un'area campione dell'unità idrogeologica del Salento (Puglia), costituita da un vasto acquifero carbonatico mesozoico. Tale area, rappresentativa sia degli aspetti idrogeologici tipici delle zone di alimentazione del Salento sia degli effetti dell'antropizzazione, è sede di nurnerosi pozzi adibiti ad uso potabile. Lo studio è stato finalizzato alla redazione della carta della vulnerabilità dell'acquifero con ii metodo SINTACS. La natura sperimentale dell'applicazione è legata alle peculiarità dell'acquifero salentino e all'assenza di esperienze pregresse per tale contesto. Sono stati effettuati rilievi diretti, prove idrogeologiche e piü cicli di campionarnento idrico ed analisi di laboratorio. I centri di pericolo sono stati censiti sulla base delle banche dati disponibili ed ispezionando ii territorio. L'infiltrazione si è dirnostrata molto rapida, anche laddove l'acquifero non affiora. La vulnerabilità è risultata notevole, da alta a molto elevata. La qualita delle acque, per quanto tuttora buona, si è dimostrata sensibile alla posizione e all'azione dei centri di pericolo. I rischi di degrado qualitativo sono risultati non trascurabili.

Factors controlling seismic susceptibility of the Sele valley slopes_ the case of 1980 Irpinia earthquake re-examined

Most of the documented slope failures triggered by the 1980 Irpinia earthquake (Ms 6.9) occurred in the upper Sele valley epicentral area (southern Italy). The early investigations revealed some puzzling characteristics of the slope failure distribution, i.e. (i) the higher landslide concentration on the valley slopes located farther away from the earthquake fault; (ii) the predominance of re-activations over first-time movements. The analyses of factors controlling the landslide concentrations indicates that the differences in hydrological setting and in slope were the two main causal factors whereas the seismic shaking, according to the radiation pattern modelling, could have been characterised by a relatively low rate of decrease across the valley. The aspect of the slopes did not play a significant role. The differences in groundwater conditions between the western and eastern valley sides were likely enhanced by the earthquake. In addition to the probable pore-water pressure rise, the seismic shaking caused large increases in flow of springs draining the western aquifer, and this made the adjacent flysch slopes more prone to landsliding. Data from available literature suggest that the effects of earthquake-induced groundwater release on seismic landslide distribution is especially important for normal-fault events. The Sele valley case also indicates that the slope of the pre-existing landslides is an important factor controlling their susceptibility to seismic re-activations.

Subsidence in the karst of Apulia (southern Italy) is described in this paper. The carbonate rocks that make up the geological structure of the Apulia region, one of the classical karst areas of Italy, are affected by subsidence, that may occur with different typology and intensity depending upon geological, topographical, and hydrogeological conditions. In particular, we have identified phenomena of inland subsidence and coastal subsidence. Inland subsidence is generally restricted to the presence of individual cavities produced by dissolution of soluble rocks underground_ in either empty, or partly or totally filled with deposits, caves, subsidence may occur, causing severe effects on the above anthropogenic structures, if present. Coastal plains of Apulia, with particular reference to its southernmost part (Salento Peninsula) are, on the other hand, interested by karst subsidence whose main feature is the development of compound sinks extending for several thousands of square meters, or the formation of individual, mostly circular, dolines along the coast lines. The occurrence of one or the other of the above features seems to depend upon topographic conditions, and their relation with the sea level oscillations as well.

Seven landslide dams of old seismic origin in southeastern Sicily (Italy)

Nicoletti P.G., Parise M., 2002, Seven landslide dams of old seismic origin in southeastern Sicily (Italy), Geomorphology (Amst.) 46 (2002): 203–222.,

This paper focuses on origin, morphology and evolution of seven landslide dams in southeastern Sicily. These landforms are part of a set of 146 landslides recently recognised in this area, which was hitherto considered to have little or no slope instability. Southeastern Sicily consists of a plateau (the Hyblaean Mountains) incised by canyons and surrounded by lower lands. It is underlain mostly by subhorizontal, moderately to well- lithified carbonate rocks. Relief is low. Several lines of evidence justify the assumption of a seismic trigger for the landslides in this area_ (1) the geo-climatic environment is not favourable to landsliding, (2) low-angle basal shear surfaces are very frequent, (3) landslide distribution is consistent with the known magnitude-distance relationships for earthquake-induced landslides, (4) historical documents testify to earthquake-triggered slope instability and (5) a specific landslide can be exactly dated. The phenomena illustrated here include six rock slides (one with a debris-flow component) and one rock fall. Slip surfaces are mostly non-circular. Landslide volume ranges from about 50,000 m3 to 34,000,000 m3. With reference to the Costa and Schuster [Geol. Soc. Am. Bull 100(1988) 1054] classification of landslide dams, five cases belong to type II (spanning the entire valley), and two to type IV (failures from both valley sides, with frontal or side contact between failed masses). With reference to the Crozier and Pillans [Catena 18 (1991) 471]classification of landslide lakes, all cases show a main valley lake while tributary valley, back and supra lakes are sporadically present. One damming is attributable to the 1693 earthquake with certainty; another damming, to the same earthquake with high probability. Three dams were reincised, one breached or reincised, one is slightly reincised and two more or less intact; correspondingly, five silting up deposits were reincised, one is being reincised at present and two are still under formation.

Old, large, and dormant landslides were unexpectedly found in southeastern Sicily, a territory of known seismicity but commonly considered as landslide-free or almost so. Purposely undertaken investigations revealed that_ (1) these landslides are scarcely compatible with the local geoclimatic environment; (2) they usually show low-angle basal shear surfaces, despite the fact that the properties of the forming material are generally good; (3) they fulfil the known relationships between earthquake magnitude and epicentre-landslide distance; (4) sources coeval with high- energy historical earthquakes occurred in 1169, 1542 and 1693 testify to the occurrence of earthquake-triggered landsliding; and (5) documentary material (presented here for the first time) correlates with certainty a specific landslide to the 1693 earthquake. This geological and historical evidence, accompanied by the absence of contrasting elements, leads us to conclude that these landslides are earthquake-triggered. Because of their typological and geometrical characteristics, nearly all landslides can be reactivated, which presents serious implications in terms of hazard, particularly with respect to lines of communication. Obviously, every action aimed at preventing or mitigating risks must start from the awareness of the causative processes, a condition substantially unsatisfied at the moment in SE Sicily. The paper concludes by emphasising the opportunity not to trust excessively beliefs that, although shared, have never been really checked.

During the Space Shuttle Endeavour mission in October 1994, a remote-sensing campaign was carried out with the objectives of both radiometric and polarimetric calibration and ground truth data acquisition of bare soils. This paper presents the results obtained in the experiment. Polarimetric cross-talk and channel imbalance values, as well as radiometric calibration parameters, have been found to be within the science requirements for SAR images. Regarding ground truth measurements, a wide spread in the height rms values and correlation lengths has been observed, which has motivated a critical revisiting of surface parameters descriptors.

Abstract

Computer techniques such as Geographic Information Systems are applied to the evaluation of the vulnerability of a deep carbonate aquifer. The study area, of about 150 km2, is located in the low Murgia Plateau (Apulia) and characterized by Mesozoic limestone and dolomite rocks of several thousand meters thickness. A wide and thick aquifer resides in these carbonate rocks. Its groundwater flows toward the sea mainly under pressure and with maximum piezometric level of about 200 m a.s.l.. Due to their high quality, the water resources of this aquifer are particularly valuable for the local communities and therefore must be protected from pollution and inappropriate use. The vulnerability map of the aquifer is an indispensable tool for the effective management of groundwater resources and to support environmental planning. Several approaches have been proposed by different authors to evaluate intrinsic vulnerability. Most of the methods for detailed vulnerability mapping are based on the integrated analysis of several variables using different algorithms. Geographic Information Systems are advanced computer tools for the analysis of georeferenced data in 2D and 3D and can be effectively applied to the implementation of evaluation models. In this study the SINTACS evaluation method was implemented in a GIS and a digital vulnerability map produced. The different data taken into consideration in this analysis, such as depth to water, actual infiltration, pollution attenuation capacity of unsaturated zone, land cover, hydrogeological features of saturated aquifer, hydraulic conductivity, terrain slope, geology and geological structures, were georeferenced and converted into digital form. Each variable corresponds to a separate data layer made of graphic and attribute data. The computerized multilayer analysis performed by the GIS is time effective and leads to more comprehensive and accurate results with better spatial resolution.

L’evoluzione dell’inquinamento salino delle acque sotterranee della Murgia e del Salento

In order to assess the evolution of seawater intrusion and the resulting saline Contamination, the trends of the 0,5 g/l isohatine over three time lags (1981, 1989. and 1997) were compared, since, at First approximation, water whose salinity is equal or lower than the above value is salt contamination free. In large areas along the Adriatic and lonian shoreline groundwater saline contamination is resulted to be a long-standing phenomenon. Only the Murgia interior and a restricted strip in the middle of the salentine peninsula have not been contaminated so far. From 1981 to 1989, the reference isohaline was reported to recede gradually. Then, the phenomenon either stopped or was reversed, as was the case in some Murgia and salentine areas, where, however, sorn additional withdrawals of the isohaline have occurred. The increasing saline Contamination in the salentine peninsula is confirmed by the evolution of the chlorine ion concentration (a parameter which indicates seawater contamination) over thirty years in eighteen wells. The analysis of data shows that the increased groundwater saline contamination is closely related to overdrafts. Before 1980. no significant concentration increase was reported in the majority of wells. The phenomenon became apparent in the late 80s after some dry years that result in a reduced recharge of aquifers and increased groundwater withdrawals. However, a less marked rise in salinity has been reported over the past thirty years.
