The purposes of a reservoir flood control operation are to decrease the flood peak stage downstream and to
store enough floodwaters in the end of operation. In this study, we investigate rational operation decisions
through formulating a reservoir flood control optimization model with linguistic description of requirements and
regulations, and using the genetic algorithm (GA) to search a global optimum of a mixture of mathematical and
nonmathematical formulations. Due to the great number of constraints and flood control requirements, the proper
penalty strategy is proposed to guide the GA searching process. The proposed approach is applied to the
Shihmen reservoir in North Taiwan for finding the rational (optimal) hydrograph as a case study. To demonstrate
the effectiveness of the proposed approach, the simplex method was performed. The results demonstrated that a
penalty-type genetic algorithm can be satisfactorily used in reservoir flood control planning to provide rational
hydrographs for two purposes of flood operation, reducing flood damage and increasing final storage.
