Reservoir Operation for Water Conservation

摘要

This research project is an effort to determine the importance and magnitude of evaporation losses in multi-reservoir systems. Computer programs HEC-3 and RESEVAP were used. RESEVAP incorporated a dynamic programming algorithm to determine operating policies for a two-reservoir system. For a given deterministic sequence of hydrology, the program can determine operating policies which satisfy one of three possible objectives: (1) Minimize cumulative evaporation; (2) Minimize cumulative spill; and (3) Minimize cumulative evaporation plus spill. The physical and hydrologic reservoir system characteristics which influence evaporation vary greatly nationwide. The basis of this research project was to simulate the operation of the two-reservoir system as modeled by RESEVAP and actual reservoir systems as modeled by HEC-3 in each of three distinct geographic regions representing arid, semi-arid, and humid locations.
