Connectivity and colluvial sediment dynamics in the Saldur River basin, Eastern Italian Alps
We present an integrated approach that aims to: (i) document the spatial distribution of mass-wasting activity and sediment production in the Saldur River basin (97 km2); (ii) detect causal linkages between mass-wasting intensity and the potential spatial distribution of discontinuous permafrost; (i...
