Abstract : This program simulates the sequential operation of reservoir systems for flood control and conservation purposes. Water quality analysis includes water temperature, three conservative and three non-conservative constituents, dissolved oxygen and a phytoplankton option. The flows to be released are determined by the program to meet at-site and downstream control point requirements. Twenty reservoirs, forty control points and any length of study period can be simulated on hourly, daily, or monthly intervals. Reservoir inflow and quality are routed through the reservoir and the minimum allowable discharge for all downstream needs is computed. The discharge and all intervening local in-flow are routed to all control points downstream of the reservoir. The thermal simulation of the reservoir and river system uses the equilibrium temperature approach. Violations of control point water quality requirements are minimized by mixing reservoir discharges from the different vertical levels allowed at the intake structure. This program is a direct expansion, in subroutine form, of the water quantity portion of computer program HEC-5.
