Popis: In the western Belgian coastal plain, a major part of the water demand is supplied by catchments in the dune belt, where water is extracted from fresh groundwater lenses in the unconfined aquifer. Because of overexploitation, mainly in summer, the water catchments are threatened by salt-water encroachment. Artificial recharge of the catchments could be considered since, in winter, a large amount of fresh surface water of the polder area is evacuated to the sea. A proposal for an improved water management of the region is formulated. Preliminary studies consisted of two tests: an artificial recharge test in the dune area and a double pumping test in a sandy ridge near a canal in the polder area. The tests are interpreted by means of inverse models. Results of the artificial recharge test demonstrate that recharge is feasible for the water catchment area of Koksijde. Results of the double pumping test show that the Avekapelle creek ridge in the polder area is very well suited as an intake area.
