| Abstract | One of the traditional and effective flood protection measures is the use of storage areas. By their controlled filling and emptying, inundation risks for downstream areas with higher vulnerability can be reduced. They not only have an influence on the flood level, but also on the residence time of the water in the river ecosystem, which is an important biological parameter. A good prediction of storage flow is therefore necessary in an integrated ecosystem model. In such model, which is being developed by the universities of Ghent and Antwerp, and where biological, biogeochemical and hydraulic processes are coupled.In this paper, a one-dimensional hydrodynamic module of the integrated STRIVE (STReam RIVer Ecosystem) model, which is based on the Saint-Venant equations and solved by the Preissmann scheme, is adapted to be able to include flow exchange with storage cells and the river is controlled by weirs (flooded river banks). Connection between storage cells is also made possible. Special attention will be paid to the propagation of the flood wave through the river system. |
