Environmental Impacts of Drainage Water Reuse on the Freshwater of El-Salam Canal (Egypt). (Dept. C)

In Egypt, the Water Quality of fresh waterways, especially those receiving wastewater from agricultural drainage such as El-Salam Canal is every, now, and then, precarious for some water use. Although, Egypt relies on this marginal quality in order to cover resulting gap between needs supply. The reuse appears be one most promising, practical, economical means increasing Egyptian budget which Government has been looking for. use mathematical models assessments waterways can considered effective practical assessment tools. This paper simulates self-purification controlling Bahr Hadus Drain (BHD) using QUAL2K model. three-step approach, Drain, was simulated with proposed hydraulic structures (I.e., weirs) at certain locations. Three different weir types were investigated fixed height Then best type first step selected simulation second a specified location and, impact quality. It concluded that there correlation depth velocity improvement dissolved oxygen. third step, logarithmic regression have developed describing relationship < /strong>
