Potential Landslide-Generated Water Waves, Libby Dam and Lake Koocanusa, Montana; Hydraulic Model Investigation.
Abstract
A hydraulic model, constructed at an undistorted scale of 1:120, reproduced about 1 mile upstream of the dam and about 1200 ft downstream of the dam for the purpose of determining the magnitude of wave heights, runup, and overtopping of the dam for four potential landslides. These potential landslides were located from 160 to 2100 ft upstream of the dam and contained potential landslide volumes of about 900,000 to 4,750,000 cy yd.
