6. One paragraph description of your model (e.g. abstract from report or paper); RGM is a physically-based, spatially distributed model for simulating meltwater flow through snowpacks. It uses a finite difference scheme for computing the energy balance conditions of the snowpack, as well as for the routing of the produced excess meltwater downslope. Time steps can be selected by the user (typically 1 hour). The model uses a recursive approach to split the time interval into two parts, if the non- linearity of the processes are too strong. This enables to regard short- term processes as well as such ones acting on the regular time scale. >>50. Please provide references relevant to the model description and use.
