This project provided a geological assessment of an area near the Red Sea shoreline. The ground there comprises alluvial fan deposits — mainly sand, with a few clay pockets. It was investigated using electrical resistivity tomography together with borehole lithology logs, with the ERT determining the subsurface resistivity distribution of the underlying deposits.
The investigated area was divided into two parts. Onshore, twelve 2D ERT profiles were collected using a Wenner-Schlumberger array. Offshore, a marine resistivity survey using floating electrodes collected a further ten 2D ERT profiles.
