Abstract

Groundwater is a sacred source of water in Egypt. It is required to do evaluation studies for the aquifers being used to monitor and evaluate its conditions for any risks. Such evaluation studies require the use of both GIS techniques and numerical models . This paper presents an evaluating approach to discuss the potential of groundwater in Sadat city. The core of this research is using GIS techniques and Numerical modeling to understand the current state of the aquifer. The GIS techniques are used to feed the numerical models with the required inputs. Numerical models were used to give a close insight to the study area hydro geologically. The numerical models were calibrated in 1990 to start the calibration in the steady state . Another calibration was done in 2017 for the transit state to calibrate the current state . After ensuring that the models accurately stimulate the aquifer. 3 different scenarios were implemented on the model. The different scenarios showed huge depression of groundwater levels in 2025 and 2030 but with different levels according to each scenario. A chemical analysis was performed on 4 water samples within the study area. A potential map was created based on a qualitative approach. High numbers of TDS were found in the large extraction areas in the south border of the study area. Due to that the eastern side of the study area became a moderate potential aquifer and the rest of the aquifer became a low potential aquifer.
