ResumoAs a part of the groundwater management masterplan for Dithmarschen, a region in North Germany near the North Sea, a multi layer model was implemented to optimize and coordinate the development and management policies of seven public and industrial waterworks. A complicated geological and hydrogeological situation, characterized by several glacial geological processes, had to be abstracted to become input for the numerical multi layer model. The model included large marsh regions, surface drained by distributed patterns of field ditches, which were simulated by an areal leakage boundary condition. A successful calibration of different model parameters has been achieved by performing a stepwise calibration according to the priority of influence. The model has been used to simulate several management alternatives, and global as well as regional water balances have been evaluated.
