ABSTRACT
Western Nile delta is an important agricultural and industrial area in Egypt, in which the government has later established new reclamation projects, and irrigation and drainage networks. The increased in the reclaimed land area together with decrease in surface water discharge specially in the 1980’s lead to shortage of surface water. Knowing that most of the reclaimed area lies over the Nile delta aquifer, increase in abstraction took place which might cause great damages for the ground water aquifer. The damage in the aquifer results in water level depression in most of wells, increase salinity and increase the salt water intrusion coming from the northern boundary (the Mediterranean). The objective of this study is to carry out an integrated management of water resources at Western Delta. As a first stage towards the integrated management, a complete data base for the existing discharge and water levels in the canals and drain networks is to be collected. Then a three dimensional numerical groundwater flow model should be established. The model should take into consideration the interconnection between the surface water flows in the canals and drains networks and the groundwater levels in the area. The model should simulate the Delta aquifer in order to help estimate groundwater availability and water levels in response to pumping and potential future droughts. The model was calibrated by matching observed and simulated groundwater levels for steady state condition. The model performed well in representing the water level contours of the aquifer in response to the amount of recharge from irrigation, waterways and abstraction of wells at the steady state. Sensitivity analyses for several parameters were carried out. |
