Simulation of the August 1979 sudden discharge of glacier-dammed Flood Lake, British Columbia
Abstract
In August 1979 a glacier outburst from Flood Lake, British Columbia, released 150106m3 of water. The resulting flood was routed through the Stikine River and yielded a maximum discharge rate of 1200m3s1 at a gauging station 90km downstream from the glacier dam. We have used a computer model to simulate this outburst in order to test the usefulness of the model as a predictor of flood magnitude. The predicted peak discharge is 2160m3s1 at the outlet tunnel of the ice dam and 1700m3s1 at the gauging station.
