“…These studies include the Tiber (Tevere) River Delta near Rome (Milli et al, 2013), the Arno and Serchio river mouths in Tuscany, west of Pisa (Amorosi et al, 2009a(Amorosi et al, , 2013, and the Volturno coastal plain, north of Naples . Similar studies have also been carried out along the Ionian Sea coast by Tropeano et al (2013). Contrary to the abundance of incised-valley systems from the Tyrrhenian Sea coast, poor documentation of paleovalley systems exists from the Adriatic area.…”

Exploitation of Amplitude and Phase of Satellite SAR Images for Landslide Mapping: The Case of Montescaglioso (South Italy)

Pre-event and event landslide deformations have been detected and measured for the landslide that occurred on 3 December 2013 on the south-western slope of the Montescaglioso village (Basilicata Region, southern Italy). In this paper, ground displacements have been mapped through an integrated analysis based on a series of high resolution SAR (Synthetic Aperture Radar) images acquired by the Italian constellation of satellites COSMO-SkyMed. Analysis has been performed by exploiting both phase (through multi-image SAR interferometry) and amplitude information (through speckle tracking techniques) of the satellite images. SAR Interferometry, applied to images taken before the event, revealed a general pre-event movement, in the order of a few mm/yr, in the south-western slope of the Montescaglioso village. Highest pre-event velocities, ranging between 8 and 12 mm/yr, have been recorded in the sector of the slope where the first movement of the landslide took place. Speckle tracking, applied to images acquired before and after the event, allowed the retrieval of the 3D deformation field produced by the landslide. It also showed that ground displacements produced by the landslide have a dominant SSW component, with values exceeding 10 m for large sectors of the landslide area, with local peaks of 20 m in its central and deposit areas. Two minor landslides with a OPEN ACCESS Remote Sens. 2015, 7 14577 dominant SSE direction, which were detected in the upper parts of the slope, likely also occurred as secondary phenomena as consequence of the SSW movement of the main Montescaglioso landslide.

“…This process lasted for at least six thousand years; the previous context is reasonably the C one (the sea level at Last Glacial Maximum was 120 m below the present level at the test site [61]). A: clays beneath flat marine terraces, sited at various elevations, with residual cover of sands and conglomerates or calcarenites; this enables, regarding the underlying impermeable marine clays, the long-term presence at their top of a fresh water-table aquifer; B: coastal marine plains; this is like the previous case, with a terrace that is now shaping, with some dozens of meters of sands saturated with seawater over the top of the blue clays; C: clays exposed on the deeply or gently dipping flanks of eroded terraces; fresh water does not lie over the clays, precipitation quickly runs off along the slope and capillary rise is dominant during the dry season; D: clays lying beneath a marsh cover in a salt pad, a very singular geomorphic situation, at low elevations over present sea level.…”

Studies dating almost a century relate clay properties with the structure of the diffuse double layer (DDL), where the charged surfaces of clay crystal behave like an electric capacitor, whose dielectric is the interstitial fluid. The intensity of the inner electric field relates to the concentration and type of ions in the DDL. Other important implications of the model are less stressed: this part of the clay soil system, energetically speaking, is conservative. External contribution of energy, work of overburden or sun driven capillarity and long exposure to border low salinity waters can modify the concentration of pore-waters, thus affecting the DDL geometry, with electric field and energy storage variations. The study of clay soils coming from various natural geomorphological and hydrogeological contexts, determining a different salinity of interacting groundwater, shows how the clay interaction with freely circulating waters at the boundaries produces alterations in the native pore water salinity, and, at the nano-scale, variations of electric field and stored energy from external work. The swelling and the shrinkage of clay soil with their volumetric and geotechnical implications should be regarded as variations of the electrostatic and mechanical energy of the system. The study is based on tests on natural clay soil samples coming from a formation of stiff blue clays, widespread in southern Italy. Geotechnical identification and oedometer tests have been performed, and pore waters squeezed out from the specimens have been analyzed. Tested samples have similar grain size, clay fraction and plasticity; sorted according to the classified geomorphological/hydrogeological contexts, they highlight good correlations among dry density, mechanical work performed in selected stages of the oedometric test, swelling and non-swelling behaviour, and electrical conductivity of the squeezed pore waters. The work performed for swelling and non-swelling samples shows well-defined differences; this endorse the relevance of pore-water salinity in determining the volumetric state of clay soils under overburden and specific hydrogeological border conditions, which together define a specific energetic state.
