Groundwater recharge and capillary rise in a clayey catchment: modulation by topography and the Arctic Oscillation
The signature left by capillary rise in the water balance is investigated for a 16 km2 clayey till catchment in Denmark. Integrated modelling for 1981–99 substantiates a 30% uphill increase in average net recharge, caused by the reduction in capillary rise when the water table declines. Calibration...
