Modelling the Flow of Mass and Energy within a Snowpack for Hydrological Forecasting

This paper describes a deterministic, distributed snow-melt model which has been developed for the Syst~me Hydrologique Europeen (SHE). The model is based on partial differential equations describing the flow of mass and energy through the snow. These equations are solved by an implicit, iterative finitedifference method. The behaviour of the model is investigated using data from a sub-Arctic site in Scotland.
