Abstract
Toshka project is located in a desert area where sand dunes spread making it an exhibition on a permanent basis to sand, in addition to low water velocity most of the year, and low water depth in many reaches, all these factors make an ideal environment for the growth and spread of weeds in water. The reaches affected by sand movement in Sheikh Zayed canal from kilometer 24.750 to kilometer 43.000 with different lengths. The accumulative quantities, of sand that expected to fall in Sheikh Zayed canal and its branches ranged between 221.74m3/year to 8948.16 m3/year. Differences between actual and design water levels results from deposits and low drawn water, physical and chemical properties of water and soil for canals varying from site to other. (SOBEK program) shows that the main canal required 333m3/s to reach to design water level.
