“…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.

Single Electrical Resistivity Tomography (ERT) survey was carried out in the Manor and Park Complex in Nowa Huta (Krakow Branice, Poland). It was applied at a small distance and parallel to the longer wall of a monumental building containing an empty 3 m deep basement. Analogue modelling was performed in order to recreate the field study at the proper scale. The laboratory set-up consisted of a water tank where electrodes were mounted to the particular plate, which rested on water surface. The basement model was made out of a non-conducting material. The default and robust inversions were tested and these variants were also considered with the use of numerical modelling. Laboratory experiments have confirmed that zones visible in the interpreted field section are caused by the influence of the building cellar located next to the survey line. Zones of this kind are additionally disturbed by the local geological structure. The experiment has pointed out, among others, that as the distance between the survey line and the underground body increases, the inversion results are still burdened by an object influence. Thus, similar situations can be verified with the use of analogue modelling presented in this paper or 3D numerical one.

“…The resistivity value varies regarding the age and the stage of waste degradation (2.0-100 ohm-m). Georgaki et al (2008) noted that a resistivity ranging from 0.21 to 4.00 ohm-m represents fresh organic waste saturated with leachate. When resistivity increases to between 4.00 and 20.00 ohm-m, the section represents fresh organic waste mixed with small amounts of cover material.…”

“…When resistivity increases to between 4.00 and 20.00 ohm-m, the section represents fresh organic waste mixed with small amounts of cover material. Resistivity above 20.00 ohm-m and up to 50.00 ohm-m implies that the waste has a higher inorganic content or that organic waste is older (Georgaki et al, 2008). For a measurable electrical resistivity contrast between the waste material and the background rocks, deposits, or soils, electrical resistivity measurement should be a useful method for imaging the depth and geometry of dolines filled with waste.…”

This article deals with doline degradation due to uncontrolled waste dumping in the past in the Logatec Polje in Slovenia. It introduces a concept for determining 3D geometric characteristics (shape, depth, radius, area, and volume) of formerly concave landforms (i.e., recently filled dolines) by using a combination of two methods: (1) photogrammetric stereo processing of archival aerial photographs and (2) electrical resistivity imaging (ERI). To represent, visualize, and study the characteristics of the former surface morphology (i.e., the dolines before they were filled), a digital terrain model (DTM) for 1972 (DTM1972) was made using digital photogrammetry processing of five sequential archival aerial photographs (1972, © GURS). DTM1972 was visually and quantitatively compared with the DTM5 of the recent surface morfology (DTM5, © GURS, 2006) in order to define areas of manmade terrain differences. In general, a circular area with a higher terrain difference is an indicator of a filled doline. The calculated terrain differences also indicate the thickness of buried waste material. Three case-study dolines were selected for 3D geometric analysis and tested in the field using ERI. ERI was used to determine the genetic type of the original doline, to confirm that the buried material in the doline is actually waste, and to ascertain opportunities for further study of water pollution due to waste leakage. Based on a comparison among the ERI sections obtained using various electrode arrays, it was concluded that the basins are actually past concave landforms (i.e., dolines) filled with mixed waste material having the lowest resistivity value (bellow 100 ohm-m), which differs measurably from the surrounding natural materials. The resistivity of hard stacked limestone is higher (above 1,000 ohm-m) than resistivity of cracked carbonate rocks with cracks filled with loamy clay sediments while in loamy alluvial sediment resistivity falls below 150 ohm-m. Nevertheless, the contrast is sufficient to confirm the landfilled waste in all studied dolines. Based on the resistivity values of buried waste and the proximity of furniture and paper factories in the Logatec Polje, it is assumed that the dolines are filled with organic waste, mostly wood material mixed with other waste (municipal, construction, and demolition waste), which causes the variability of electrical resistivity. environmental geology; doline degradation; waste; stereo image processing; digital terrain model; electrical resistivity imaging Received 6 March, 2013; Revised 19 November 2013; Accepted 17 December 2013 Breg Valjavec M. 2014.
