Abstract | Throughout the Rocky Mountain region, there are thousands of square miles of heavily productive watersheds lying in the alpine and subalpine zones. These areas are completely unprotected from the enormous evaporative and sublimative losses produced by wind, temperature, and solar radiation. A snowmelt runoff equation is developed using these independent variables along with soil moisture deficit and spring precipitation. The paper consists of three parts: 1) the development of evaporation and sublimation formulae; 2) automatic data processing with these formulae, wind and temperature data from Boise USWB, and Lander, Wyoming; 3) the application of this processed data to the snowmelt-runoff analysis of a watershed. Snowmelt-runoff forecasting formulae for headwater basins with alpine areas where little protection from forests is felt, must include the factors of evapo-sublimation losses along with solar radiation. |
