Remote Sensing and Geographic Information System with Geophysical Resistivity in Groundwater Investigations (West Atbara Basin–River Nile State–Sudan)

Abstract

Remote Sensing (RS) data have been widely used in combination with Geographic Information System (GIS) in groundwater resource management. Thus, (GIS) and (RS) integration tools with Geophysical resistivity are proposed to define the groundwater potential zone in the study area. Remotely sensed data of the Landsat 7 ETM+ have been used in this study. Different digital image processing techniques were applied to the satellite images to reveal the geological and hydrological aspects. The Geophysical method used in this study is electrical resistivity Vertical Electrical Sounding (VES), in this case, Schlumberger electrode array was applied. Thirty-four VESs have been conducted in the study area. The interpretation of studied data showed that the area consists of three main aquifer types: Sandstone aquifer (the best one), alluvial deposits (of minor importance) and weathered basement complex aquifer (of lesser concern).
