Optimization of Spillway Operation for Flood Mitigation in Multi-reservoirs River System
The multi-reservoirs system in Vu Gia Thu Bon rivers catchment plays a significant role in production of annually alternative electrical and mitigation of flood damage. However, in the flood season, operational problems of the rivers and multi-reservoirs system are more likely to increases which result from developing conflicts objectives and the number of reservoir. In this research, a flood mitigation operation approach based on a simulation-optimization model is developed for minimizing vulnerability of flood in downstream of the system. For this purpose, an optimization algorithm is introduced, in which maximum water level at downstream control points is objective function and the spillway release discharges are the decision variables. A global optimization tool, Shuffled Complex Evolution (SCE) algorithm which implemented in the AUTOCAL software was coupled with the Mike 11 from DHI simulation model for optimizing stages level of spillway gates. Vu Gia Thu Bon rivers catchment including four major reservoirs of A Vuong, Song Tranh 2, Dak Mi 4 and Song Bung 4 is examined in historical flood events that happened in 2009. The results show that the reservoir system using the optimal operation is more effective in reducing maximum water level at the downstream control points comparing to the current regulations.
