Natural precipitation created a fresh-water lens underneath the dunes along the North Sea. Since 1850 two permanent human interferences have had influence on the fresh-water lens: 1. the grounwater abstraction for drinking-water supply; and 2. the reclamation of the Haarlem Lake behind the dunes. The salt- and brackish-water intrusion has been known since 1904, when the deep abstraction of fresh water began. With these observations the intrusion can be modelled with a computer program. A first step is to make a "representative" cross section perpendicular to the coast. The influences of groundwater abstraction and reclamation on the salt-water intrusion can be calculated, as well as the length of the "fresh-water" tongue underneath the North Sea and the consequences of deep-well infiltration in the dune-water catchment area.
