We study the diurnal streamflow cycles in a high altitude catchment where a large field campaign has been undertaken. In one monitored sub-basin, the cycle is evapotranspiration-dominated, in another, the cycle is icemelt-dominated. The two processes happe ...
A growing population in Svalbard, reflecting an increase in scientific research and tourism, leads to an increasing amount of people exposed to avalanche danger. Consequently, there is a growing interest for a local avalanche warming procedure. The goal of ...
Purpose The aim of this study is to describe the effects of speed and gradient during uphill ski mountaineering on energy expenditure, to relate any changes to changes in stride characteristics, and to determine an optimal gradient and speed allowing minim ...
We estimate seasonal drifting snow sublimation at a study site in the Swiss Alps with the numerical model Alpine3D using external wind fields from the Advanced Regional Prediction System on a high-resolution grid (10 m). Novel in the field of snow transpor ...
Le Mont-Blanc est un site alpin de haute montagne d’une incroyable richesse de paysages et de diversités. C’est un monde à part, fascinant, séparé des vallées par son altitude, ses conditions climatiques et son accès difficile. L’architecture est un domain ...
Rockfall hazard assessment without the use of rockfall trajectory and runout zone models is unthinkable in the 21st century. Such rockfall models have existed since the sixties, but nowadays an almost confusing palette of rockfall trajectory and runout zon ...
Climbing is a challenging task for autonomous mobile robots primarily due to requirements for agile locomotion, and high maneuverability as well as robust and efficient attachment and detachment. A novel miniature wall-climbing robot is proposed. The robot ...
Robotic ground vehicles are systems that use gravity and contact forces with the ground to perform motion. In this paper we will focus on n-wheeled vehicles able to perform motion with all the wheels maintaining contact at the same time. The main goal of t ...
