Abstract: A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints. The objective of the methodology is to determine release flow rates from each lake in a system of lakes such that downstream quality targets are met as nearly as possible and specified quantity constraints are satisfied. A case study is presented illustrating the value of the technique in determining optimal release flow rates from a system of lakes. The large-scale characteristics of this problem are illustrated with results obtained on the CYBER 205 at Colorado State University.
