Abstract

A geophysical investigation has been conducted in the Abu Simbel region using the D.C. resistivity method. The results have been integrated with geological information in order to determine, where possible, the depth to the basement, any water-table variations, and the delineation of the hydrogeologic conditions. In this study, twenty vertical electric soundings (20 VES-es) were measured in the area. The measured geoelectric data were made utilizing different configurations (Schlumberger and Wenner) using an ABEM-Terrameter SAS300c resistivity meter. The sounding data were interpreted and analyzed by using classical curve matching and modern computer techniques. Interpretation of each curve model provides the equivalent layering in the form of n-layers with different thicknesses and true resistivities. The presence geoelectric zones with different geographic distribution. The wet zone (50 - 500 Ohm) is lying at a shallow depth with varying thickness (1- 24m) and formed as lenses. Three highly resistive lying near the surface and is made up of ferruginous sand which is an obstacle to the growing of bushes in the new farming desert lands and the third (deep) may correspond to hard rocks (e.g, basement rocks), Seven surface water samples from Khors of Lake Nasser were analyzed in the years 1999, 2000 and 2001. These samples were taken from different locations around the lake adjacent to Abu Simbel town. The hydrochemical analysis of these samples illustrated that the values of TDS and trace elements are nearly the same. It is observed that the values of TDS and trace elements increase only at the sites near the denser population communities.
