Optimal operation of an upstream reservoir for flood control Johnson, Wayne Adrian

Abstract

This thesis describes the development of a method for determining the most efficient way to operate an upstream flood control reservoir for maximum flood peak reduction at a downstream point. Linear programming is used as the optimization technique. A simplified case is studied, namely that of a single storage reservoir approximately 500 miles upstream from the area to be protected. A channel routing method which was linear was required for use with linear programming. For this reason a Muskingum type channel routing method was chosen. The results for the three years that were studied are presented in graphical form. They indicate the extent that the downstream peak could be reduced and the operation of the upstream reservoir which would be required to bring about this reduction in peak flow. Procedures for extending the technique to more complex systems and possible applications of the method are discussed.
