English Abstract This report describes the average change in the
phreatic groundwater level and to the increase or decrease of the seepage
for eight scenarios. The scenarios are composed within the framework of the
National Policy Plan for Drinking and Industrial Water Supply for the
Netherlands. Several types of groundwater abstractions are distinguished,
namely abstractions from phreatic and semi-confined aquifers and riverbank
infiltration. In the scenarios the yearly amount of groundwater is
increased or decreased, related to the abstracted quantity in 1988. The
calculations are carried out with the "Groundwater Model for the Netherlands
(LGM)".
