Evaluating methods for debris-flow prediction based on rainfall in an Alpine catchment [PDF]
Natural Hazards and Earth System Sciences, 2021 The prediction of debris flows is relevant because this type of natural hazard can pose a threat to humans and infrastructure. Debris-flow (and landslide) early warning systems often rely on rainfall intensity–duration (ID) thresholds. Multiple competing

Shear-thinning, Coulomb friction and grain collisions in debris-flow waterfalls: Applications of a 3D phase mixture model with a single calibration parameter and a complex 4-way coupled resolved CFD-DEM approach [PDF]
E3S Web of Conferences, 2023 Shear-thinning is a common flow-feature of fine sediment suspensions. Mixed with gravel, Coulomb friction drives the energy dissipation between small grains while collisions become more and more important with larger grains.

Simulated or measured soil moisture: which one is adding more value to regional landslide early warning? [PDF]
Hydrology and Earth System Sciences, 2021 The inclusion of soil wetness information in empirical landslide prediction models was shown to improve the forecast goodness of regional landslide early warning systems (LEWSs). However, it is still unclear which source of information – numerical models

Geological Society, London, Memoirs, 2022 Abstract In this chapter, we consider key advances in the understanding of mass movements between c. 1965 and c. 2000. This period saw a burgeoning need for a greater level of understanding of mass-movement processes in response to a series of high-impact mass-movement events, and ...

Bedload Transport Monitoring in Alpine Rivers: Variability in Swiss Plate Geophone Response
Sensors, 2020 Acoustic sensors are increasingly used to measure bedload transport in Alpine streams, notably the Swiss plate geophone (SPG) system. An impact experiment using artificial weights is developed in this paper to assess the variability in individual plate ...

Subseasonal hydrometeorological ensemble predictions in small- and medium-sized mountainous catchments: benefits of the NWP approach [PDF]
Hydrology and Earth System Sciences, 2019 Traditional ensemble streamflow prediction (ESP) systems are known to provide a valuable baseline to predict streamflows at the subseasonal to seasonal timescale.
