Fluvial transport and denudation rates in three small catchments in Eastern Iceland, Finnish Lapland and Swedish Lapland

In the alpine Hrafndalur catchment denudation rates are relatively high, with mechanical denudation dominating over chemical denudation due to high mechanical weathering rates of the low-resistant rhyolites in this area. Both the Kidisjoki and the Latnjavagge catchments are characterised by low contemporary denudation rates where chemical denudation dominates over mechanical fluvial denudation. In Latnjavagge, the low intensity of mechanical fluvial denudation is mainly due to a closed and stable vegetation cover. The low-relief area of Kidisjoki is characterised by very low mechanical fluvial denudation rates.
