Simulation of the August 1979 sudden discharge of glacier-dammed Flood Lake, British Columbia
In August 1979 a glacier outburst from Flood Lake, British Columbia, released 150 × 10 6 m 3 of water. The resulting flood was routed through the Stikine River and yielded a maximum discharge rate of 1200 m 3 s −1 at a gauging station 90 km downstream from the glacier dam. We have used a computer mo...

| Summary: | In August 1979 a glacier outburst from Flood Lake, British Columbia, released 150 × 10 6 m 3 of water. The resulting flood was routed through the Stikine River and yielded a maximum discharge rate of 1200 m 3 s −1 at a gauging station 90 km 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 2160 m 3 s −1 at the outlet tunnel of the ice dam and 1700 m 3 s −1 at the gauging station. |
