Abstract: Based on the software MIKE 11 and FEFLOW, a coupling surface water-groundwater interface has been developed to investigate the interaction for river branches, polders and wetlands. Its functionality covers the exchange of boundary conditions during runtime and the synchronisation of the temporal discretisation. The system has been applied to simple benchmark cases and complex field conditions. One project focused on the optimisation of a polder flooding system which prevents flooding in the downstream regions of the river Elbe. Due to the coupling, the influence of groundwater storage could be estimated and an optimised flooding strategy could be developed.
