Description :
This paper examined the impact of a hillslope failure on a headwater channel system in the UK uplands, Wet Swine Gill in the northern Lake District. The primary aim was to account for sediment transfer in the failure event and post-event sediment dynamics in the period 2002-2008. A multiple sediment budget approach, was used to construct 3 sediments budgets (2002, 2003-2004, 2008). Results clearly demonstrate changes in the dominance of slope erosion versus channel erosion/transfer. Discussion about the limits of this approach and the accuracy of the sediment budget models that are developed. The AA. aim also to assess the relationship between contemporary meteorological (climate) conditions and sediment system response.
