Abstract
This study follows from a previous design estimate of maximum precipitation and snowmelt in the Pembina basin, by Buckler and Quine 1971. An indirect verification is made of the original procedure for estimating basin precipitation, using Thornthwaite's method. His concept that Runoff is equal to Precipitation less Evapotranspiration was applied to a 15 year period on the Pembina. Good agreement was found with measured runoff and it is concluded that the method of estimating basin precipitation was reasonably accurate. The Generalized Snowmelt equations developed by the U.S. Army Corps of Engineers were then used to reproduce the spring hydrograph for the Pembina for 1956. Only a fair simulation was obtained, probably because of the inability to allow for the diversion of snowmelt to surface storage. A comparison of the calculated snowmelt volume and measured runoff during the snowmelt period was made for 5 years. Only 23% of the calculated snowmelt appeared as direct runoff in the snowmelt period.
