Systems analysis to reservoir design in the James River Basin

Abstract

A probabilistic linear programming model was used to find preliminary designs for two multi-purpose reservoirs in the upper James River basin. Requirements of flood control, water quality maintenance, and recreation in the upper and middle basins were considered through the year 2020. The preliminary designs were then evaluated by simulation using synthetic streamflow. A technique for generating synthetic streamflows was developed which combined features of several existing models. Results showed that for water quality requirements to be met through 2020 in the middle basin (Lynchburg), 98% BODS removal for all waste discharges will be required by the year 1980, even with both reservoirs in operation. In the upper basin (Covington), water quality requirements cannot be met in 1980 or thereafter even with 98% BODS removal and the upper reservoir in operation.
