Aerial photography and stereoscopic examination under high magnification of the acquired BW airphotos have been utilized in planning groundwater prospecting in seven areas in Nubia on the eastern side of the River Nile which serve as examples for arid areas in the world. The lithologie units, drainage, as well as lineaments and photolineations have been delineated and characterized with the help of previous Landsat imagery interpretation of Nubia environs. The lithologie units serve to determine the types of groundwater aquifers and aquicludes within the units, and their sure and probable extensions. The drainage lines are instrumental in following the courses of the accumulation of rainfall and the final destination of the runoff water. In addition, the delineation of the lineaments and photolineations in the lithologie units and the recognition of their features help in the location of lineaments intersections favourable as sites for groundwater prospecting. The aquifers in the studied areas are distinguished into those present in Cretaceous bedded sandstones, in fractured and foliated igneous-metamorphic rocks, as well as in Quaternary alluvium and wind-blown sand, the last case is not treated in the present work. Optimum utilization of the first aquifer type is inhibited by its hydraulic conductivity which is not normally high enough to allow quick replenishment to the wells. Furthermore, groundwater storage and movement in the second type are governed considerably by lineaments developed within the concerned rock units. In the final analysis favourable lineaments intersections represent the best chance for finding water in the second type while these intersections enchance groundwater recharge in the first type. |
