Short summary

As land use influences hydrological processes (e.g., forests have a high water retention and infiltration capacity), it also impacts floods downstream in the river system. This paper demonstrates an approach quantifying the impact of land use changes on economic flood damages: damages in an initial situation are quantified and compared to damages of simulated floods associated with a land use change scenario. This approach can be used as an explorative tool in sustainable flood risk management.
