A flood mitigation control strategy based on the estimation of hydrographs and volume dispatching

摘要

Flood events are expected more frequent with biggest magnitude in the near future. They have potential big impacts on human economic activity and property, on health and life of man, and on the environment. One possibility to mitigate the flood impact consists in using flood storage areas and in designing a control strategy to dispatch the volumes of water and reducing the flow peak. The designed mitigation control strategy is based on the prediction of hydrographs and the estimation of the water volumes that have to be stored. It leads to optimal flow peak reduction according to the capacity of the flood storage areas. This paper details the steps of the proposed approach. Then, a realistic case-study is considered to illustrate the designed flood mitigation control strategy.
