Abstract The environmental issues have become of great concern because the water supply system relies heavily on groundwater as main sources for extensive and continuous processing of reclamation development as occurred, especially in the southern portion of Western Nile Delta desert fringes. The extracted groundwater for those areas based on the nonrenewable moghra aquifer which characterized by limited thickness and lack of recharge. This leads that there is a continuous decline in the groundwater levels with groundwater quality degradation associated with groundwater development lands. Accordingly the Ministry of Water Resource and Irrigation (MWRI) planned to implement surface water projects in groundwater development areas (critical areas) (255,000fed.), covering the black spots of Western Nile Delta fringes by constructing piped three canals branches out from Rossetta branch and Rayah el Nasery. To shift from the groundwater as single source used in water resource planning and management to integrate water sources as conjunctive use. The most urgent issues to be addressed are thus the water requirement, the economic pumping depth to the groundwater,productivity,and groundwater quality (salinity and pollution) which can be reflected by quantitatively and qualitatively groundwater potential. This leads that Continuous monitoring and evaluation water policy making is imperative and a dynamic subsequently the continuous groundwater development process in which the proposed water policy should be checked and updated according to changes in the social or the economical conditions. In this dissertation, an attempt has been made to describe the criteria and methodologies to understand and evaluate the quantitative and qualitative groundwater potential. The methodologies mainly based on the aerial discritization per unit cell (cell wise) covers the whole exiting and expected development areas of Western Nile Delta fringes. |
