Abstract
El-Salam Canal is a major national Egyptian project operating according to mixed water. A portion of the drainage water flowing into Lake Manzala from the drains (Farasqur, El-Serw and Bahr Hadous) is added to the fresh water of El-Salam Canal to increase the volume of water required to irrigate 620,000 feddans of the newly reclaimed land.This Study aims at assessing and evaluating the water quality throughout studying the variation of concentrations of important water quality parameters (Biological Oxygen Demand, Dissolved Oxygen, Total Dissolved Solids , Ammonia , PH, Iron) along El-Salam Canal and its feeding sources, Studying Bahr Hadous water demand to El-Salam Canal, suggesting alternative new water sources to improve water quality and finally Proposing different scenarios for water mixing processes to improve water quality of El-Salam Canal. The results of the study show that El-Serw and Bahr Hadous drains have the main effects on increasing the concentrations of BOD and NH4 in El-Salam Canal. Damietta Branch has a secondary effect on increasing the concentration of BOD in winter and NH4 in summer. Bahr Hadous drain is the main source on increasing TDS and Fe in El-Salam Canal after El-Salam Pump Stations (2and 3) particularly in winter. Treatment for drainage water of Bahr Hadous, El-Serw and Farasqur drains and pre-treatment of industrial wastes at the source are necessary to improve water quality of El-Salam canal. Also The results indicate that there is a water deficit is expected in Bahr Hadous drain in July each year, equals 1.78 million cubic meters per day. El-Taweel Bahry and Kebly drains can be taken as alternative new sources mixing with Nile fresh water by ratio 1:1 to compensate this water deficit or reuse in time of need. The available water quantity that can be reused is 568.0 million cubic meter / year with treatment.
