Abstract

Seawater intrusion is an important environmental problem in the coastal aquifers of many Mediterranean countries. In the 438 sq km Korba aquifer in eastern Tunisia, a large increase in the number of pumping wells for irrigation purposes since the 1960s has resulted in significant lowering of water table levels in several observation piezometers, and in a consequent deterioration of water quality. Due to the important agricultural uses of the Korba plain, several remediation scenarios are being considered for this region, including artificial recharge of the aquifer and construction of small reservoirs to serve as an alternative source of irrigation water. In order to investigate the impact of these measures on aquifer water quality, a modeling study supported by a geographic information syste
