DETERMINATION OF OPTIMAL FLOOD CONTROL LEVELS IN A MULTI RESERVOIR SYSTEM

In this study, a water resources system with multi-objective and multiple reservoirs is described. Optimization model used to the technique of dynamic programming with successive approximation (DPSA) for short term planning is established on this system. The Ceyhan River Basin is selected for application in the model. In the model, used the flow data of the flood hydrograph with design-objective (Probable maximum flood (PMF) hydrograph with 100-year-frequency), minimization of the peak value of the flow data released from reservoirs is achieved, and inflows released from one reservoir to other reservoir are carried by routing with kinematic wave approach in river. In the minimization, objective function is three stages, related to the maximum safe discharge for downstream and the additional control volume aimed to flood control. In the result of this optimization process, optimal flood control levels are obtained monthly.
