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)".
