Flooding due to rivers overflowing have affected this year many countries in the world. The engendered problems, due to their intensity, are relative to goods and persons safety, and often cause a sharp increase of the insurance costs, which is no more tolerable in the actual economic context. To prevent these problems, it is necessary to limit water heights downstream the streams. In the literature, numerous described works were done on flows modelling and management. The work presented in this paper, is interested in the quantitative management by means of floods diversion areas placed along the river and for which location and sizing are known. A management method computing the height of gates opening at each time step is proposed. The strategy is based on a transportation network model of the flood diversion area system including the time transfer delays. It allows the computation of the water volumes to be stored in time. Simulation results for different flood episode are discussed.
