6. The snow melt/accumulation model is based on a modified degree-day method and provides the equivalent amount of melted/accumulated water for each gridcell of the catchments considered. The method developed allows modelling of the melt/accumulation processes directly without requiring information about observed snow cover distribution in the area. Measured daily precipitation was converted to equivalent rainfall using minimum and maximum daily temperature and modelled equivalent snow depth (in mm of water), accumulated in each particular gridcell for each day. River's runoff was modelled using as an input the equivalent rainfall estimated by the snow melt/accumulation module and the mean daily temperature in each gridcell integrated over the whole catchment. The modelled snow depth and duration of the snow season were compared with point measurements of snow depth at several stations. The modelled and measured streamflow data were compared as well. These charachteristics are used as a criterion of model quality. 50. Schreider, S.Yu., Jakeman, A.J., Whetton, P.H., Pittock, A.B.

Unfortunately at the moment only the CRES preprint contains the model description, but JoH and AJWR papers are going to be published very soon (I recently checked proofreads).
