Electrical resistivity tomography and forward modelling in hyper-arid environments – A case study from Erg Chebbi, Southeast Morocco

Electrical Resistivity Tomography (ERT), a non-destructive geophysical method, which aims at detecting sediment conductivity and its distribution including e.g. stratification, has been used in manifold research topics, for example in sedimentology, hydrology, and geoarchaeology. However, ERT is mostly used in humid to semi-arid environments, where at least some underground moisture guarantees reliable conductivity. In this paper, for the first...
