Simulation of the Continuous Snowmelt Process

Abstract

The efficient design of many water management projects requires the ability to predict the time distribution of runoff from a melting snowfield. A continuous model of the snow accumation and melting processes is presented for this purpose. The empirical and theoretical equations that have been used to represent these processes are integrated into a model developed to have a wide range of applicability owing to its flexible data requirements. The snowmelt model is tested using various combinations of recorded data thought likely to be available in practical design problems. A comparison of the generated values of certain important snowpack variables with those actually observed shows good agreement. Application of the model to an experimental catchment is made to estimate streamflows resulting from the computed snowmelt. Although the results were favorable, suggestions are made as to how they may be improved.
