Alternative Approach of Wind Driven Optimization for Flood Control Rule Curves
Rule curves of reservoir are necessary guides to operate reservoir system in the long run for both
flood and draught control. This study proposes the alternative approach of Wind Driven Optimization (WDO)
technique to connect with simulation model for searching optimal reservoir rule curves as the flood control area.
Minimum average excess water was used as the objective function for searching procedure. The synthetic
inflow data of 1,000 events and future inflow were used to evaluate efficiency of the flood control rule curves
which showing by situations of water shortage and excess release water in term of frequency, magnitude and
duration. The proposed model has applied to determine the optimal flood rule curves of the Nam Oon Reservoir
in the Northeast Region of Thailand. The results have shown that the pattern of the obtained rule curves similar
to the current rule curves. The optimal flood control rule curves were used to simulate the Nam Oon Reservoir
system for evaluating the situation of flood in long term operation. The results have indicated that the
situations of flood of the optimal flood control rule curves are smaller than theirs current rule curves both
present situation and future situation.
