AB: This study describes research using both the USDA Snowmelt-Runoff Model (SRM) and the CASA (Carnegie- Ames-Stanford) ecosystem model coupled with a surface hydrologic routing scheme to validate and generate daily forecasts for snowmelt runoff in California mountain watersheds. To assess CASA's ability to estimate actual water flows in both extreme and non-extreme precipitation years, we have compared gridded model results with gauge station data throughout the state and with predictions from the SRM. Satellite remote sensing studies of land cover types and snow cover extent are presented for selected watersheds in the Sierra Nevada Range of California. This research supports the development of a near-term (4-6 weeks) forecast system for snow melt runoff and flood potential from California mountain watersheds.
