Snow in a very steep rock face: accumulation and redistribution during and after a snowfall event

Frontiers in Earth Science, 2015
Terrestrial laser scanning was used to measure snow thickness changes (perpendicular to the surface) in a rock face. The aim was to investigate the accumulation and redistribution of snow in extremely steep terrain (>60°).

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

Ecography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Optical determination of snow density via sub-surface scattering

Communications Physics
The physical properties of snow, such as its stiffness, reflectivity, and thermal conductivity, are critical components in feedback processes of the Earth’s system and useful proxies for various applications in environmental science, ranging from ...

On the relation between avalanche occurrence and avalanche danger level [PDF]

The Cryosphere, 2020
In many countries with seasonally snow-covered mountain ranges warnings are issued to alert the public about imminent avalanche danger, mostly employing an ordinal, five-level danger scale.

Proglacial lake records of Holocene glacier behaviour and catchment processes in Slettedalen, Northeast Greenland

Journal of Quaternary Science, EarlyView.
ABSTRACT Constraining Arctic catchment response to Holocene climate change is vital for understanding future environments. We present detailed sedimentological, geochemical and grain size end‐member analysis of two Holocene (~7.0 ka to present) lake sequences, S1 and S2, close to Zackenberg, Northeast Greenland.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River 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.

A casting method using contrast-enhanced diethylphthalate for micro-computed tomography of snow

Journal of Glaciology, 2021
Casting snow is necessary to prevent metamorphism and deformation prior to X-ray micro-computed tomography (μCT) imaging. Current methods are insufficient for large-scale field sampling of snow due to safety considerations associated with the casting ...

Deep ice layer formation in an alpine snowpack: monitoring and modeling [PDF]

The Cryosphere, 2020
Ice layers may form deep in the snowpack due to preferential water flow, with impacts on the snowpack mechanical, hydrological and thermodynamical properties.

Regulatory Framework and Public Policies for Sustainability in the Construction Sector

Sustainable Development, EarlyView.
ABSTRACT This study analyzes the role of public policies in promoting socially responsible practices in the construction sector, with a particular focus on their contribution to climate neutrality and the decarbonization of the building stock. European agreements exert increasing pressure to transform the construction sector, reinforcing the transition

Snow redistribution in an intermediate-complexity snow hydrology modelling framework [PDF]

The Cryosphere
Snow hydrological regimes in mountainous catchments are strongly influenced by snowpack heterogeneity resulting from wind- and gravity-induced redistribution processes, requiring them to be modelled at hectometre and finer resolutions.
