Résumé partiel
The present thesis concerns with detailed geomorphologic, geologic, hydrogeologic and hydrogeochemical settings of wadi Qena basin. It also deals with the effective factors on the development of water resources in the study area. Wadi Qena basin occupies an area of 15455 Km2 and extends in northeastsouthwest direction discharging its water in River Nile. It lies between latitudes 26° 15´ 00” & 28° 15´ 00” North and between longitudes 32° 15´00” & 33° 30´33”East. The average annual precipitation over Wadi Qena basin was extracted from 3-hourly, Tropical Rainfall Measuring Mission (TRMM), precipitation data over a period of 15 years (from 1998 to 2013). It decreases from 13.43 mm/y on the eastern part of the study area to 2.78 mm/y on the western parts. Geomorphological features, the study area is divided into several land features. These features are the high lands (watershed areas) and low lands (water collectors). The first includes ; the Red Sea mountainous terrains, the high plateaus (El Maaza limestone and El Ababda sandstone), the low plateau and hilly area. The low lands include the morphotectonic depressions, piedmont plain and drainage networks. The general characteristics and hydrogeological significance of these units are explained. Wadi Qena main basin and its tributaries are morphometrically analyzed. Assessment of the flood strength and hazard degrees of the studied sub-basins relative to each other is also calculated. Geologic setting : Stratigraphic succession, in the present study, special attention has been paid to the stratigraphic setting of the water bearing formations especially Nubia sandstone and Quaternary deposits where both of them represents the main aquifers in the study area. The lithologic sequence and rock exposures along Wadi Qena basin range in age from Precambrian to Quaternary.
