✦ Synopsis

Seasonal. local and monthly vertical variations in physical and chemical characteristics of Aswan

High Dam Lake (AHDL) were followed during the period from March 1982 to February 1984 . The results show that there were distinct seasonal thermal variations . Similarly. thermal stratification was evident from late spring through early autumn . Oxygen content appeared t o vary with the changes in pH value . Water transparency in the southern part was greatly reduced by the incoming silt laden flood especially in summer months . consequently. nitrate-nitrogen and total residue increased considerably in this part during summer . The recorded minimum N-concentration ( 2 . 3 5 ~8 1-1) was certainly limiting the growth of phytoplankton . Suspended and organic matter exhibited somewhat irregular variations a t least during the period of this study . 2 2 Int . Revue ges . Hydrobiol . 74 (1989) 3
