Abstract

Hasholt, Bent: Late Autumn Runoff and Sediment Transport in a Proglacial Drainage System, Sermilik, East Greenland. Geografisk Tidsskrift 93:1–5. Copenhagen 1993. Field investigations of runoff and sediment transport were carried out in the proglacial area of the Mitdluagkat Glacier drainage basin in September 1992. Runoff in the proglacial stream was 32 l/s/km2. Runofffrom the northern flank of the glacier at the outlet of Lake Kugssuag was 14 l/s/km2. Mean daily sediment transport was 17 t/d in the proglacial valley and 0.2 t/d at the outlet of the lake. It was clearly demonstrated that the formation of frazil ice and anchor ice caused increased sediment transport, dominating the total load of the proglacial stream during the measuring period 2/9–19/9.
