Abstract:
A snow melt model is postulated to utilize rawinsonde observations of temperature, dewpoint, and wind speed as input variables. The model is developed around the snow surface energy balance, with the energy budget components structured to accommodate the upper air data. Some physical characteristics of the watershed are incorporated as parameters in the model. Rawinsonde data from Winslow, Arizona and stream flow data from a small watershed near Flagstaff were used to develop and test the model. The snow melt runoff process was modeled by a linear regression equation using the computed snow melt values as independent variables. Data from two snow melt seasons were used to estimate the regression coefficients and to refine the parameters in the snow melt model. Runoff was then predicted for two independent snow melt seasons and compared with the observed runoff. An analysis of these independent seasons suggested that the energy balance components could be modified to more adequately utilize the rawinsonde data, and that variable solar radiation term should be included. The utility of the snow melt model was not conclusively demonstrated by this study. The short snow melt runoff seasons resulting in a limited data base and an over-simplified runoff model are possible reasons for the lack of verification.
