Motivation In snowmelt dominated river basins, snow properties near peak accumulation are used to assess spring and summer runoff. Forecast models rely on estimates of the water stored in the snowpack to determine the contribution of snowmelt to runoff. Current operational runoff forecasts (DWR & NWS) assume stationary relationship between sparse point measurements of snow water equivalent and runoff Spring runoff forecasts use snow course measurements taken near the 1 st of each month Analysis of snow course measurements show non-stationarity ie. trends Howat and Tulaczyk (2005) find decreasing and increasing SWE trends dependent on both latitude and elevation
