The Environmental Effects of the High Dam at Aswan The Environmental Effects of the High Dam at Aswan INTRODUCTION: The livelihood and stability of Egypt `s population is directly linked to the Nile valley and delta. Although these two regions account for less then 5% of Egypt `s land surface (fig. 1), all its agriculture and water sources are concentrated in these areas (White 1988). The water sources for the Nile are the Blue Nile (originating at Ethiopian highland) and the White Nile (draining east central Africa and Sudan).The river flows through Egypt toward the Mediterranean sea, forming a delta at its south-east coast. Fig. 1 - The Nile path after building the Aswan high dam. (White 1988). Prior to the beginning of emplacement of barrage along the Nile in the last century, the river had a seasonally fluctuating fluvial regime (Hurst 1964). Its annually water discharge at the coast was above 8*1010 m3, caring about 10*108 tons of sediments (Eldardir 1994), and was the main sediment source for the east Mediterranean (Stanley and Wingerath 1996). At the end of the 19th century two major sediment bearing distributors were active (Damietta and Rosetta, fig. 2) (Stanley 1996).
