Lowering the head of an artesian aquifer in Zealand, Denmark by pumping of groundwater is shown to affect the water balance.
Based on known amounts of groundwater being developed, the coefficient of transmissivity was determined and in combination with piezometric maps the net outflow of groundwater was computed for the pre-pumping period as well as for the pumping period.
The annual streamflow was found to decrease considerably and the groundwater recharge to increase by the same amount.
