Landsystems of the tropical high Peruvian Andes: Glaciers, lakes, wetlands and water resources in the Cordillera Vilcanota

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Calculation of Snow Avalanche Runout Distance [PDF]

Annals of Glaciology, 1983
Distance of maximum avalanche runout is calculated by four topographical factors. An empirical equation found by regression analysis of 206 avalanches is used to predict the maximum runout distance in terms of average gradient of the avalanche path (angle α).

Characterisation and multiphase flow modelling of a rock avalanche turned into a supraglacial debris flow: Insights from Mt Job, British Columbia, Canada

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Photographs before (left) and after (right) the May 2023 landslide in Mt Job, Mount Meager Volcanic Complex, British Columbia, Canada. The initial rock avalanche impacted the glacier, producing a 4.5‐km‐long debris flow that ran over it and down the valley.

Estimating the effective elastic modulus and specific fracture energy of snowpack layers from field experiments

Journal of Glaciology, 2016
Measurements of the mechanical properties of snow are essential for improving our understanding and the prediction of snow failure and hence avalanche release. We performed fracture mechanical experiments in which a crack was initiated by a saw in a weak

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Improving Fully Distributed Snowpack Simulations by Mapping Perturbations of Meteorological Forcings Inferred From Particle Filter Assimilation of Snow Monitoring Data

Water Resources Research
Snow plays a crucial role in the water balance of mountainous regions by affecting the timing and magnitude of runoff and, thus, water availability and flood hazards.

On the Flow of Avalanching Snow [PDF]

Journal of Glaciology, 1977
Abstract Variation of flow depth of a flowing avalanche caused by a change in the slope angle is examined using Bernoulli’s energy equation, used in hydraulics to determine a non-uniform steady flow. This equation is modified for a material with internal friction and a strongly curved track.

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Snow Water Storage Within Eight Pacific Coastal Watersheds in British Columbia (Canada) Inferred From Four Years of Airborne Lidar Data

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Maritime mountain snowpacks are among the least understood and most poorly quantified components of global snow water storage, despite their vital role in sustaining water supplies and ecosystem health. Here, we present a 4‐year record of snow mass distribution across eight small‐to‐medium‐sized (5.2–63.4 km2) watersheds within the coastal ...

Glide-snow avalanches: a mechanical, threshold-based release area model [PDF]

Natural Hazards and Earth System Sciences
Glide-snow avalanches release at the ground–snow interface due to a loss in basal friction. They pose a threat to infrastructure because of the combination of unreliable mitigation measures, limited forecasting capabilities, and a lack of understanding ...
