Aim

The purpose of this project is to check the accuracy of the floodplain boundaries set by the flood hazard maps using various ecological data and to then compare the floodplain extent caused by frequent or less frequent floods. Subsequently methods are developed to quantify selected ecosystem services within the given floodplain areas, such as nutrient and flood retention, carbon storage, agricultural production, building material production and biodiversity. Various data sets are used, which are processed with the help of geographic information systems. As a spatial reference hydrological units, namely river catchments, form the basis for comparing the floodplains with more or less frequent flooding. Catchment areas offer the advantage that, with the help of gauges, runoff data can also be used and the importance of floods in recent years can be taken into account.
