Unformatted text preview: 3/26/2008 1 Presentation by Karl Rittger Presentation by Karl Rittger This work is supported by Naval Postgraduate School Award N00244 ‐ 07 ‐ 1 ‐ 113 and NASA Cooperative Agreement NNG04GC52A Motivation y 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. y Current operational runoff forecasts (DWR & NWS) assume stationary relationship between sparse point measurements of snow water equivalent and runoff y Spring runoff forecasts use snow course measurements taken near the 1 st of each month y Analysis of snow course measurements show non ‐ stationarity ie. trends y Howat and Tulaczyk (2005) find decreasing and increasing SWE trends dependent on both latitude and elevation Snow Water Equivalent in the Sierra Nevada Can we improve runoff forecasting by integrating remote sensing sources?...
