A distributed physically based model of the entire land phase of the hydrological cycle has been developed for the Susa-area, covering about 1,000 km 2 of Zealand, Denmark. The model is described in part I of the paper, also presented in this volume. The model9s ability to simulate the streamflow depletion caused by a groundwater abstraction from a confined aquifer, overlaid by Quaternary drift deposits, has been tested on historical streamflow data from the catchment of Koge A. This catchment has been heavily influenced by a major groundwater abstraction started in 1964. The physical mechanisms of streamflow depletion are discussed, and the effects of a groundwater abstraction on the recharge to the confined aquifer and on the streamflow are illustrated. General conclusions regarding streamflow depletion due to groundwater abstraction are made.
