Description
Summary:Suspended sediment concentration and discharge measurements from the proglacial stream Linnéelva are reported for a three week period during the 2006 melt season. This period included a threshold discharge event in which suspended sediment concentration increased dramatically, resulting in 25% of total monitored sediment transport occurring in less than 3% (15 hours) of the total monitored time period. This appears to have been a sediment flushing event, with the system displaying sediment exhaustion following the peak in discharge and suspended sediment concentration. Denudation rates are estimated based on the calculated 1.41 million kilograms of suspended sediment transported by Linnéelva during the monitored time period. Based on this study, denudation in the upper part of the Linné valley is between 90mm/1000 yr and 350mm/1000yr.
