Ice Jam Analysis at Idaho Falls, Snake River, Idaho

Abstract

The cause of ice jams on a reach of the Snake River upstream of the City of Idaho Falls, Idaho, was investigated. The relationship between ice jam flooding in a residential area and the reconstruction of a hydroelectric facility downstream was determined. Different configurations of the hydroelectric facility (new facility, old facility, and interim period) under open water and ice-covered conditions were accomplished using the HEC-2 backwater profile computer code with its cover option. Recommendations for ice jam flood control were made and actions were taken by the City of Idaho Falls.
