Abstract:To reduce flood risk along large rivers, measures have to be implemented to increase their flood conveyance capacity. These measures provide opportunities for ecological restoration of floodplains. However, it is expected that vegetation development in renaturated floodplains strongly increases upstream water levels. To fill up the lack of practice-oriented quantification methods in this field, a GIS-based hydraulicecological model is developed that describes this relationship in a mathematical way. This model closes the gap between vegetation, as it is mapped or predicted by vegetation models, and roughness coefficients that are used by hydraulic models. Furthermore, the feedback of the changing water levels on vegetation predictions is studied to assess the significance of this feedback mechanism.
