Snowmelt contribution to mean annual stream flow of South Island river reaches

The snow melt estimates were generated through the separation of daily precipitation into rainfall and snowfall components to provide 1981-2010 mean annual snowfall and rainfall maps. The ratio of the catchment-based accumulation of these precipitation components was then found for each river reach in the New Zealand River Environment Classification (REC), which is equivalent to the ratio of snow and ice melt to flow. The REC user guide is available at: http://www.mfe.govt.nz/environmental-reporting/about/tools-guidelines/classifications/freshwater/rec-user-guide-2010.pdf Kerr, T. 2013: The contribution of snowmelt to the rivers of the South Island, New Zealand.
