Controlling spillway gates of dams is a complex, nonlinear, non-stationary control process and is significantly affected by hydrological conditions which are not predictable beforehand. In this paper, control methods based on dynamic fuzzy control are proposed for the operation of spillway gates of dams during floods. The proposed methods are not only suitable for controlling spillway gates but also able to maintain target water level in order to prepare a draught. In the proposed methods, we use dynamic fuzzy control that the membership functions can be varied by changing environment conditions for keeping up the target water level, instead of conventional static fuzzy control. Simulation results demonstrate that the proposed methods based on dynamic fuzzy control produce an accurate and efficient solution for both of controlling spillway gates and maintaining target water level defined beforehand.

The purposes of the reservoir operation during flood period are the reduction of the flood damage in the downstrem reaches and the conservation of flood control for the later use. This paper presents a model of simulation technique to determine the real-time operating rules on an hourly basis. The objective of strategy is to minimize the miximum release through the spillway gates with consideration of the uncertainties associated with the forecasted inflows. In this paper, a general procedure for solving this problem is described for a single and paralle reservoirs.
