Modification of the Tangborn short-term hydrometeorological model, with trial results from the Baker River basin, Washington

This report presents a modification of the short-term hydrometeorological model (Tangborn, 1978) for estimating river-basin snowmelt runoff. A multiple linear regression replaces a nonlinear regression scheme to correct for temperature effects of snowmelt runoff. Results based on data from the Baker River basin, Washington, indicate that model performance is improved by the modification in a majority of applications, and, additionally, use of the model is simplified and computer time is reduced.
