Résumé
The Egyptian government has planned to develop new areas in the Nile valley fringes. This study evaluates the feasibility of groundwater development plans for El-Minia governorate. Groundwater modeling is used as a tool to address management issues and provide alternative groundwater withdrawal scenarios for maximizing the benefits of the groundwater resources. The Nile valley water system in El-Minia governorate is described using a regional groundwater model that covers the entire governorate. This regional model is calibrated to head measurements at 1992 under steady state conditions. The model is then verified in a transient mode where the model predictions between 1993 and 2006 are compared to head measurements available in these years. Subsequently, four local models for newly proposed reclamation areas in the fringes are developed and calibrated to boundary fluxes obtained from the regional model and local head measurements. The models are used to develop management charts that provide decision makers with the tools necessary for managing the system and achieving the desired development goals. Results indicated that there are interaction between groundwater aquifer system and surface water system. Future withdrawal scenarios in the new reclamation areas are developed and evaluated. It is found that the groundwater resources in the four new areas can provide as much as 40,000 m3/day with a maximum drawdown of about 8 m. The cultivated area in these cases ranges between 100 and 2000 Feddans.
