Innovative control strategy for flood mitigation through a combination of barrage management on impounded rivers and polders

The research work presented here aims to provide a detailed investigation of various ways of potentially reducing peaks: adapted barrage operation, polder operation, a combination of both, and the simulation-based development of complex control specifications.

The results of the study show that barrage management can contribute to flood reduction on the Inn River. In the field of flood protection and retention, barrage management is generally a complementary measure to, for example, retention areas and polders. The positive interaction with the operation of an exemplary polder in the direct area of application of barrage management and the high water level reductions at neuralgic points of the Inn and in the confluence area of the Inn and Danube, which emerged from the investigations, impressively illustrate the possible synergy effects of different flood protection measures.
