Abstract:

This study examines how hypothetical changes in irrigation practices affect downstream hydropower sites. Dynamic programming and simulation techniques are coupled to determine optimal combinations of irrigation efficiency and diversions which maximize energy revenue from downstream hydropower sites. The coupled optimization-simulation model is applied and the results presented for a study area in the upper Missouri River Basin in south-western Montana. The effects of anticipated changes in irrigation efficiency and diversions are evaluated. The results are intended to guide water resource administrators who administer water rights in the study area and operators of downstream reservoirs who may want to revise operating policies as changes in irrigation efficiency or diversions take place.
