GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.2 GNGTS 2024 Discussion The obtained results, which will be presented during the 42 nd Natonal Conference of the GNGTS 2024 in Ferrara (Italy), clearly demonstrate that conductve textle sachets electrodes can be successfully used to collect reliable ERT datasets in environments with debris and coarse-blocky surface, decreasing the tme requested to deploy the investgaton line. Consequently, applying this alternatve electrode approach in future ERT measurements performed on rock glaciers, would allow to acquire measurements more rapidly, and the opportunity to collect more survey lines (e.g. realizaton of pseudo-3D geometries) extending the characterizaton of the investgated mountain permafrost area. eferences Bast, A., Wilcke, W., Graf, F., Lüscher, P., and Gärtner, H.; 2015: A simplifed and rapid technique to determine an aggregate stability coefcient in coarse grained soils, CATENA, 127, 170-176, htps://doi.org/10.1016/j.catena.2014.11.017 .
