Abstract

Glacial river discharges were monitored during 5 summer expeditions (2000-2003 and 2005) to Petuniabukta (central Spitsbergen), a High Arctic island in the Svalbard archipelago. This paper aims to document and classify the different types of floods in glacier-covered catchments as well as their triggering mechanisms. Four types of meteorologically driven floods were distinguished, depending on the seasonal variations in the dominant water supply source and the type of storage. They were induced by : spring/summer snow-melt; mid-summer ice and snow-melt; rainfall events; föhn phenomena. Additionally, sudden water drainage from ice-dammed lakes of varous origins may generate amounts of discharge surpassing total annual discharge. These floods are considered the main agents of proglacial relief remodelling, sediment transport and deposition
