DOI: 10.1038/s41598-025-10463-7

Abstract: Electrical resistivity tomography (ERT) provides valuable subsurface structural information but often relies on inverted resistivity thresholds for interpretation. Inversion inherently produces smooth boundaries that can lead to interpretation ambiguity, especially in delineating clay boundaries critical… read more here.
