APPLICATION OF GEOPHYSICAL TECHNIQUES FOR ENGINERING PURPOSES AND DELINEATING THE.UND ERGROUND WATER AT NEW TIBACITY LUXOR, EGYPT

Abstract

The New Tiba City is one of the new promising areas and was selected to be a natural expansion of Luxor City in future. This .area lies between latitudes 25°43'00" and 25°46' 00" Nand longitudes 32°45' 00" and 32°47'00" E. The present study was aimed to evaluate and delineate the underground water and the geotechnical properties of the foundation rock materials, in addition to define the possible lithological succession and strUctural implications in the study area. To achieve these goals, the following steps were done:

1- The available geological, geomorphological and subsurface hydrogeological conditions were collected from the previous studies. 2- Thirty four shallow vertical electrical soundings were carried out to evaluate the subsurface section into layers and determining the thicknesses, resistivities, lithologies, water bearing formations and the structural implications of the study area. Also to help in engineering geological investigation of sites prior to construction by determining the depth to rockhead for foundation and give information on the degree of saturation of subsurface materials. 3- Three dipole-dipole profiles were performed along the proposed housing area; profile "A" with a length of 900 m, profile "B" with a length of 315 m and "C" profile with a length of 300 m. These dipole­ dipole profiles to evaluate the cavings or any archeological features.
