Abstract

Daily runoff from snow melt is based on degree days over a 24-hr period. A degree day is one degree over 32deg F for 24 hours. Mean temperature at one station is used and curves have been drawn relating melt in inches of water to the mean temperature at different altitudes. Another curve relates inches of melt to runoff during each part of the runoff season. The method is almost entirely empirical and neglects several factors. The procedure is applicable in regions developing semi-permanent snowpack during the winter and in basins where extreme elevations restrict melting at any instant to a limited portion of the snow cover.Discussion is included by R.A. Work.
