Complex and rugged topography induces large variations in erosion and sediment delivery
in the headwaters of alpine catchments. An effective connection of hillslopes with the …

This paper presents an overview of the recent geomorphological and hydraulic insights on
the dynamics of steep mountain streams, here defined as those channels with slope> 4–5 …

Upon their discovery in 2000, Martian gullies were hailed as the first proof of recent (ie less
than a few million years) flowing liquid water on the surface of a dry desert planet. Many …

In the Dolomitic region, abundant coarse hillslope sediment is commonly found at the toe of
rocky cliffs. Ephemeral channels originate where lower permeability bedrock surfaces …

Sediment connectivity within a catchment depends largely on the morphological complexity
of the catchment and is strictly related to the anthropogenic modification of the landscape. In …

Digital elevation models (DEMs) built from repeated topographic surveys permit producing
DEM of Difference (DoD) that enables assessment of elevation variations and estimation of …

Torrent control works, such as grade control dams and sediment retention dams, are
structural measures for controlling debris flows and debris floods. In spite of the widespread …

The study of fast geomorphic changes in mountain channels and hillslopes, driven by
intense geomorphic processes, requires frequent and detailed topographic surveys. In the …

Debris-flow activity in a watershed is usually defined in terms of magnitude and frequency.
While magnitude–frequency (M–F) relations have long formed the basis for risk assessment …

Debris-flow monitoring in instrumented areas is an invaluable way to gather field data that
may improve the understanding of these hazardous phenomena. A new experimental site …
