Abstract
The human impact on regional groundwater systems is investigated in the Dijle
basin, situated east of Brussels, Belgium. The hydrological and hydrogeological
settings are rather complex because the land-use is strongly affected by
urbanisation, industrialisation and agriculture.
The effect of land-use on the groundwater recharge is simulated with the
WetSpass model, which allows one to estimate spatially distributed runoff,
evapotranspiration, and recharge as a function of land cover, soil type and
topography. In order to quantify the impact of urban and agricultural land-use,
the results are compared with the hypothetical situation in which all land cover is
assumed to be forest. The results show a substantial reduction in groundwater
recharge especially in urban areas.
