Joint press release by German Environment Agency and German Federal Institute of Hydrology (BfG)
Envisioned measures under the National Flood Control Programme are said to be effective
Simulations indicate severe flooding along Danube, Elbe and Rhine rivers could be considerably reduced in the event of a future emergency
Better supra-regional flood protection is possible, say the results of a five-year research project carried out by the German Federal Institute of Hydrology (BfG) on behalf of the German Environment Agency (UBA). The project evaluated the effectiveness of the envisaged measures in the national flood protection programme (NHWSP) for the Danube, Elbe and Rhine river basins. The measures would be able to reduce the water levels of future large floods by between 10 and 50 cm over long stretches, and even significantly more under certain circumstances. Overall, the NHWSP measures in all three river basins show considerable supra-regional effectiveness. The almost 70 measures examined include dike relocations, flood retention basins and polders which can provide the rivers with room to spread (floodplains) and, in some cases, absorb and retain considerable volumes of flood waves.
