Reconstruction of historic soil erosion rates in a small lake catchment of the Melrakkaslétta peninsula of northeast Iceland using tephrochronology and ground-based LiDAR data
Erosion rates within the small catchment of an endorheic basin located in the upper Fremridalur (NE-Iceland) were quantified using a combination of borehole data, tephrochronology, terrestrial LiDAR and GIS techniques. Despite the great distance of the study area to the volcanic centers active durin...

Erosion rates within the small catchment of an endorheic basin located in the upper Fremridalur (NE-Iceland) were quantified using a combination of borehole data, tephrochronology, terrestrial LiDAR and GIS techniques.

A continuous increase in sediment accumulation rates during the last c. 6,100 years is observed. The total volume of the sediment within the basin and the sediment yield of the catchment were determined using a digital elevation model derived from terrestrial laser scanning and a modelled layer of underlying bedrock.
