GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.2 GNGTS 2024 reconstruct the three main geological units of the study area (Fig.3d) and highlights the beneft of the joint approach, as cluster no. 3 ends abruptly at x = 81 m rather than extending endlessly towards last part of the secton. Figure 3. Field case study at the Penne dam (Central Italy): (a) individual inversion, (b) cross-gradient joint inversion, (c) normalized cross-gradient, (d) fuzzy c-means clustering. Conclusions A cross-gradient algorithm to jointly inverted ERT an SRT data on structured mesh incorporatng topography was presented. The beneft of the proposed approach was quanttatvely evaluated in terms of a new standardizaton of the cross-gradient parameter to assess the impact of the coupled scheme and a fuzzy c-means analysis to improve the fnal interpretaton phase.
