Abstract: Snowmelt is an important addition to flood modeling in mountainous regions and other areas where snowmelt plays a large role in the overall surface water influx. This project made use of the Utah Energy Balance (UEB) Grid model in order to quantify snowmelt data in near real time. The UEB Grid model is an energy balance model and uses three state variables: water equivalence, energy content, and age of the snowpack surface. The model uses meteorological, climatological, and geospatial data as gridded inputs. This project uses the Goddard Earth Observing System Model V.5 (GEOS-5), and MODIS, TERRA, and TRMM satellite data products. The study area for this project was the Upper Green River Basin watershed. Future plans are to incorporate the UEB Grid model outputs into flood prediction models on a global scale.
