GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.1 GNGTS 2024 stability and accuracy of the proposed approach, even if each sounding is independently inverted without explicit spatal constraints (Zaru et al. 2023). Verifcaton against boreholes and comparisons with deterministc results highlights the reliability and efciency of the proposed strategy. Moreover, the probabilistc approach inherently provides an estmaton of the uncertainty of the results that is quite problematc in deterministc framework.
