Abstract : A reregulation dam is used to reduce drastic fluctuations from main reservoir releases, usually as a consequence of hydropower operations. In a pumped-storage system, it also provides storage for subsequent pumpback to the upstream reservoir. This report describes the expected impact of the addition of a reregulation pool system. A cost-effective method for simulating the hydrodynamics and transport in a reregulation pool is presented. The method has been coupled with a vertical one-dimensional reservoir model to simulate the hydrodynamics and transport of the reservoir-reregulation pool system. The modeling procedure for simulating the hydrodynamics and transport of the reregulaiton pool was selected from three candidate methods. The three methods in progressive order of complexity are: (1) the sump method, (2) the level pool routing method, and (3) the finite difference simulation of the Saint-Venant equations. The methods have been incorporated within the WESTEX model, and the predicted temperature profiles in the main reservoir and the release temperatures from the regulation pool are compared to results from a reservoir study previously conducted at the Waterways Experiment Station.
