Optimization of Abstraction Wells near Coastal Zone
Abstract:
Groundwater management in coastal aquifers is crucial for protecting these aquifers. The seawater intrusion affects coastal aquifer salinity, especially with groundwater abstraction. The overall objective of this research is to investigate the impact of abstraction wells on the groundwater salinity and drawdown in a coastal aquifer in Damietta, Egypt. This research includes a number of scenarios: different abstraction-well arrangements, depth of the well-screen, abstraction rates, installation of injection wells and application of surface recharge. The approach employed in this research was based on a set of field investigations and numerical modelling. Groundwater flow simulation and seawater intrusion numerical modelling was completed to predict the changes in aquifer salinity with time for these scenarios. According to the seawater intrusion simulation and some testing scenarios, the results indicated that the recommended scenarios are those corresponding to installation of injection wells and surface recharge application scenarios. The impact of seawater intrusion could also be reduced by arrangement of abstraction wells in order to maintain salinity concentrations for aquifer locations far from the shoreline.
