Landslides, debris avalanches and flows are common events in mountainous regions,
causing tremendous damages to people and infrastructures. Their dynamics are …

Sediment composition and bed morphology are two crucial factors that can significantly
affect the dynamics of debris mixtures and attendant entrainment characteristics. In this …

The incompressible-rheology with low-Stokes-number experiments, which incompressible
models fail to describe. The combination of granular rheology, pore pressure and drag …

Dense granular flows can spontaneously self-channelise by forming a pair of parallel-sided
static levees on either side of a central flowing channel. This process prevents lateral …

Sedimentary structures deposited from dilute pyroclastic currents are largely dominated by
the products of metre‐scale dune bedforms containing backset lamination. Since the first …

Submarine landslides may generate super-tsunamis as they interact with water bodies such
as oceans, mountain lakes or reservoirs. These water bodies may contain solid objects …

Flow-like landslides are one of the most catastrophic types of natural hazards due to their
high velocity and long travel distance. They travel like fluid after initiation and mainly fall into …

Seven lunar crater sites of granular avalanches are studied utilizing high‐resolution images
(0.42–1.3 m/pixel) from the Lunar Reconnaissance Orbiter Camera; one, in Kepler crater, is …

Snow avalanches are typically initiated on marginally stable slopes with a surface layer of
fresh snow that may easily be incorporated into them. The erosion of snow at the front is …

Two cases are presented wherein the main flow pattern in sand traps changes considerably
as a function of discretization scheme, grid resolution and turbulence model. Both cases …
