Identification of snow cover depletion patterns in the Boise River Basin using satellite imagery. Project no. DACW68-83-M-5737 Item Info

The purpose of this research was to develop snow cover area maps for the Boise River Basin in Idaho. Landsat satellite imagery was used as the basic data source for the development of these maps. The snow covered area information on the Landsat imagery was transferred to 1 to 250,000 scale U.S. Geological Survey topographic maps using optical projection techniques with the aid of the zoom transfer scope. This research is the first phase of a larger project in which snow covered area maps will be used to enhance the predictive capability of the SSARR model. This model is used by the Walla Walla District of the U.S. Army Corps of Engineers as a river flow forecasting model for the Boise River Basin. In past years there have been some problems with the predictive capabilities of the model during later stages of spring snow melt runoff. It is felt that an improved model could be developed by comparing model predicted with actual snow covered areas and snow line elevations. This report outlines the required future studies and identifies the budget requirements to make these refinement studies.
