Subglacial cavity collapses on Swiss glaciers: Spatiotemporal distribution and mass loss contribution

open access: yesJournal of Glaciology
Glacier collapse features, linked to subglacial cavities, are increasingly common on retreating Alpine glaciers. These features are hypothesized to result from glacier downwasting and subsurface ablation processes but the understanding regarding their ...

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

Influence of meteorological factors, snow properties and climatic changes on evaporation from the snow cover surface

open access: yesВодное хозяйство России: проблемы, технологии, управление, 2023
The contribution of evaporation from the surface of the snow cover to the water balance of the land surface is a little-studied area of hydrology. Th e growing relevance of these studies increases with climate warming and more active involvement of the ...

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Snowpack properties vary in response to burn severity gradients in montane forests

open access: yesEnvironmental Research Letters, 2019
Wildfires are altering ecosystems globally as they change in frequency, size, and severity. As wildfires change vegetation structure, they also alter moisture inputs and energy fluxes which influence snowpack and hydrology.

Snow and ice in hydrology

open access: yesEos, Transactions American Geophysical Union, 1973
Joint symposia on the role of snow and ice in hydrology, sponsored by Unesco and WMO, were convened concurrently in September 1972 at the Banff School of Fine Arts, Banff, Alberta. Opening of the sessions was appropriately marked with an early season snowfall.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.
