Groundwater Exploration using Integration of Electrical Resistivity Data with Remote Sensing and GIS Data, Northern State –Sudan

Abstract

Remote sensing and GIS studies have been utilized and aimed to reveal the geological, topographical aspects, as well as to decipher the main lineaments, structural and paleo-drainage patterns. Electrical Resistivity measurements have been carried out in form of Vertical Electrical Sounding (VES) to show water bearing formations and the aquifer thickness. Remote sensing data revealed general elevation range between 154–588 m (a.m.s.l.), general slope is from North to the south and several primary paleo-drainage systems are clear depicted, the drainage system runs from the south-east to north-west. Resistivity data showed that aquifers are of good permeability and of regional recharge. The recommended depths of the boreholes to be drilled are ranging from 180 m to 240 m
