Abstract Sustainable river basin management often requires an integrated understanding of surface-subsurface flow and transport processes. The software framework OpenGeoSys (OGS) and the EPA Storm Water Management Model (SWMM) have been coupled to accomplish this. In this work OGS simulates flow in confined and unconfined aquifers applying the Darcy equation, while surface channel runoff is described with the Saint-Venant approach using EPA-SWMM. Aquifer and river are coupled via exchange fluxes. The sensitivity of the simulation results is examined in reference to a leakance parameter in the calculation of coupling source terms. The application of the coupled model to a real-life case study (Poltva catchment, Western Ukraine) is outlined.
