SELECTION OF STREAMFLOW AND RESERVOIR-RELEASE MODELS FOR RIVER-QUALITY ASSESSMENT.

Sound water-resource planning requires consideration of realistic alternatives. Digital models, based on hydraulic and hydrologic principles and utilizing adequate input data, can be used to simulate the response(s) of a water-resource system to various alternatives. Streamflow and reservoir modeling methods are reviewed, including a discussion of general data requirements. Guidelines for model selection are presented with both hypothetical and actual studies used to illustrate possible selection procedures. Refs.
