Sediment Transport During an Outburst from Glacier De Tsidjiore Nouve, Switzerland, 16–19 June 1981

Abstract

AbstractBetween 16 and 19 June 1981 a large water pocket of volume 183 000 m3burst from glacier de Tsidjiore Nouve. From hourly stream discharge and suspended sediment concentration observations a suspended sediment output of 1 674 × 103kg was calculated. The transport of bed-load was estimated at 3 840 × 103kg, hence a total quantity of around 5 500 × 103kg of sediment were removed from the catchment, including the pro-glacial field, in the four days of the outburst.
