Description
This study is focused on simulating snowmelt runoff for the Weber River Basin using the US Department of Agriculture Snowmelt Runoff Model (SRM). The Weber River Basin covers 6400 square kilometers within the Great Salt Lake Basin, Utah. Major inputs to the SRM are temperature, precipitation, and snow covered area (SCA). The USGS DEM (10 m) is used to delineate and characterize the Weber basin. SCA is estimated from standard MODIS satellite data products. The MODIS 8-day binary product, SNOWMAP (MOD10A2), and daily fractional snow cover (FSC) (MOD10A1 FSC) will be used for the SCA estimation. The MODIS instruments on the NASA Terra and Aqua spacecraft provide snow cover observations on a daily basis when cloud cover permits over the globe as well as for regional and local areas. However, most MODIS daily products contain cloud cover that hinders accurate snow cover estimation. Therefore, 8-day composite products as SCA inputs, are used and compared to the daily FSC products. In addition, MODIS daily land surface temperature data (MOD11A1) will be used to validate the temperature input. Most results are obtained using WinSRM, ENVI/IDL and ArcMAP. Major issues involved in the modeling will be presented. The ultimate objective of the research is to assess the utility of MODIS observations in snowmelt runoff prediction.
