Past changes in natural and managed snow reliability of French Alps ski resorts from 1961 to 2018 [PDF]

, 2021
Abstract. Snow reliability is a key climatic impact driver for the ski tourism industry, for which there is more literature regarding future projections than past observed impacts. This study provides an assessment of past changes in natural and managed snow cover reliability from 1961 to 2018 in the French Alps.

Probability Calibration Of Load Duration Modification Factor For Timber Roofs In The Polish Mountain Zones

Archives of Civil Engineering, 2014
The resistance parameters of timber structures decrease with time. It depends on the type of load and timber classes. Strength reduction effects, referred to as creep-rupture effects, due to long term loading at high stress ratio levels are known for ...
