Abstract

On 12 August 1997, the lower part of Diadem Glacier in the southern Coast Mountains fell into Queen Bess Lake and produced a train o large waves. The waves overtopped the broad end moraine at the east end of the lake and flooded the valley of the west fork of Nostetuko River. The displacement waves also incised the outflow channel across the moraine. Stratigraphic and sedimentologic evidence supports the conclusion that the flood had two phases, one related to wave overtopping and a second to breach formation. Empirical equations were used to calculate the peak discharge of the flood at various points along the west fork of the Nostetuko valley and to describe the attenuation of the flood wave
