Analyzing Instream Flow Tradeoffs for Small Hydropower Development
Enviromental Policy and Law of Instream Flow
A multi-objective optimization model is used to analyze tradeoffs between net power revenues from hydropower development and the environmental benefits of instream flow. The model also incorporates an instream flow objective using a methodology that relates changes in stream discharge to a target-response variable such as habitat, fish biomass, or standing crop. In maximizing net power revenue and instream benefits, the model solution gives optimal penstock diameters and monthly hydropower diversions and instream flows in each river reach. Hydropower development on the Logan River in northeastern Utah was used as a case study to demonstrate the application of the model. The model results show the feasible alternatives and identify Pareto optimal alternatives that should be the focus of instream flow negotiations regarding economic and instream flow benefits.
