Aswan area is one of the important areas in Egypt and because it encompasses the vital engineering structure of the High dam, so it has been selected for the present study. The Aswan High Dam is considered as a unique structure among all the large irrigation and electric power project in the world. This paper deals with using micro-gravity, precise leveling and GPS data for geophysical and geodetically studies. For carrying out the detailed gravity survey in the area were established for studying the subsurface structures. To study the recent vertical movements, a profile of 10 km length joins the High and old Aswan dams were established along the road connecting the two dams. This profile consists of 35 GPS/leveling stations extending along the two sides of the road and on the High Dam body. Precise leveling was carried out with GPS and repeated micro-gravity survey in the same time. GPS network consisting of nine stations was established for studying the recent horizontal crustal movements. Many campaigns from December 2001 to January 2012 were performed for collecting the gravity, leveling and GPS data. The main aim of this work is to study the structural features and the behavior of the area as depicted from gravity, leveling and GPS measurements. The present work focuses on the analysis of the gravity, leveling and GPS data. The gravity results of the present study investigate and analyze the subsurface geologic structures and reveal to there be minor structures; features and anomalies are taking W-E and N-S directions. The geodetic results indicated lower rates of the vertical and horizontal displacements and strain values. This may be related to the stability of the area.
