Abstract

Seismic refraction technique has been adapted to investigate the groundwater in a pilot area nearby Jabal Hafit in the southeast of the UAE. In this work, the groundwater level and the structure framework of the area been systemized. The measured water level in different wells used as control points. The results of these measurements used to confirm that the groundwater level could primarily revealed by seismic refraction in the gravely-sands or silty-clay areas. The groundwater level can be determined as a boundary of acoustic impedance by seismic refraction method [1]. When the electric properties of near surface sand and clay beds investigated, a principal obstacle recognized in applying the method of resistivity measurement to problems of water exploration. Namely, the dissociated ions of adhesive water, being an electrolyte in the case of both sand and clay, give a relatively good electric conductivity even to the "dry" ground, which will not be significantly altered by the saturation of the pore volume by groundwater. Regardless of several exceptional cases, the groundwater level does not behave as an electric boundary and cannotlocate by the method of resistivity measurement. The possibility of using the seismic refraction method determined by the elastic properties of the near surface layers [1].
