“…It has been applied for investigating areas of complex geology, such as volcanic and geothermal areas (Di Maio et al, 1998), seismotectonic structures (Caputo et al, 2003;Nguyen et al, 2005), and areas affected by hydrogeologic phenomena and environmental problems (Ogilvy et al, 1999;Lapenna et al, 2005;Soupios et al, 2007;Georgaki et al, 2007;Naudet et al, 2008). It has been also used to locate cavities in the subsoil (El-Qady et al, 2005;Gibson et al, 2007;Crawford et al, 2007;Mitrofan et al, 2008;Soupios et al, 2008).…”

Abstract. This work, carried out with an integrated methodological approach, focuses on the use of near surface geophysics techniques, such as ground penetrating radar and electrical resistivity tomography (ERT), and geomorphological analysis, in order to reconstruct the cave distribution and geometry in a urban context and, in particular, in historical centres. The interaction during recent centuries between human activity (caves excavation, birth and growth of an urban area) and the characters of the natural environment were the reasons of a progressive increase in hazard and vulnerability levels of several sites. The reconstruction of a detailed cave map distribution is the first step to define the anthropic and geomorphological hazard in urban areas, fundamental basis for planning and assessing the risk.

“…This technique has numerous possible applications when one is faced with various problems in different geological settings (Caputo et al, 2003;Colella et al, 2004). It is increasingly used in environmental studies, hydrogeology (Maillet et al 2005;Š umanovac, 2006;Martínez et al, 2009), and geotechnics (Naudet et al, 2008), among other fields. This technique has also been used for detection of natural crevice-type caves (van Schoor, 2002;Gutiérrez et al, 2009;Pá nek et al, 2010;Gambetta et al, 2011) and in some cases, to locate manmade mining cavities (Maillol et al, 1999;Martínez-Ló pez et al, 2007).…”

Abstract:We have analyzed the geoelectric response produced by three cavities cut into different geological substrata of granite, phyllite, and sandstone that had previously been characterized by direct methods. We also examined a mining void excavated in granite. In each case, we applied three different geoelectric arrays (Wenner-Schlumberger, Wenner and dipole-dipole) and several inter-electrode spacings. The survey results suggest that electrical resistivity tomography is a viable geophysical tool for the detection and monitoring of mining voids and other subsurface cavities. The results vary depending on a wide range of factors, such as the depth and diameter of the cavity, the multi-electrode array used, the inter-electrode spacing, the geological model, and the density of the data. The resolution capacity of the Wenner-Schlumberger array for the detection of these cavities was greater than that of the Wenner array and slightly better than the dipole-dipole. There is a direct relationship between inter-electrode spacing and diameter of the cavity. In general, we observed a loss of resolution as the distance between the electrodes increased. The most efficient detection was achieved when the inter-electrodes distance was less than or equal to the diameter of the cavity itself. In addition, cavity detection became increasingly less precise with its depth beneath the surface. Cavities with a radius of about 1.5 m were located by both the WennerSchlumberger method and the dipole-dipole at depths of more than 4.6 m, which means that prospecting can be carried out at depths 3 times the radius of the cavity.

“…The main factors in the triggering of landslides are heavy rainfalls or snow, together with human activities and, less frequently, earthquakes (Clarke & Rendell, 2006b;Gullà & Sdao, 2001;Naudet et al, 2008;Polemio & Sdao, 1998).…”

This paper performs denudation processes and landforms characterizing the Camastra River catchment (Basilicata -South Italy), on a 1:40,000 scale map. The map, which includes gravitational processes and landforms and water erosion processes and landforms, was obtained by combining field surveys with the analysis of topographic maps and of multitemporal aerial photos, ranging from 1954 to 2010. These latter provided information on both spatial and temporal evolution of geomorphic processes. The integration and the elaboration of the data obtained in a GIS environment provided the inventory map of denudation processes and landforms. Landslides are widespread in the study area, and play an important role in the present-day landscape evolution. A total of 953 landslides were recognized, occupying a surface of 79 km 2 , about 22% of the whole study area. The recognized landslides were mapped on the basis of movement type, as follows: slides, flows, falls and complex landslides. With regard to water erosion processes, the most evident and spectacular landforms in the study area are represented by badlands (the so called calanchi), due to concentration of running water on steep clayey slopes, producing narrow and knife-edge ridges. Finally, sheet, rill and gully erosion are particularly active on areas devoid of vegetation cover, as well as on cultivated fields. This kind of map is an useful tool for land planning policy. Also, these types of studies are basic and complementary to applied methods for investigation and mapping of land susceptibility to denudation processes, as landslides and water erosion.
