Snowmelt modelling and solutions for outdoor snow storage.

Summary

As a result of the increasing global temperatures, shorter periods of natural snow and warmer winter temperatures are threatening winter sports facilities close to the cities. Different solutions for outdoor snow storage in Granåsen [were] studied with the intention to reduce the melting loss. 24 000 m3 snow covered by sawdust will be stored from the beginning of April to the end of September. A snowmelt model was developed for calculation of the snowmelt due to heat from the ground, precipitation, the surrounding air and solar radiation. The snowmelt during the season was found to be 20 %, and the heat from the surrounding air and solar radiation constitute more than 80 % of the total melt. Increasing the thickness of the sawdust layer proves to be the solution which reduces the snowmelt the most. However, a thicker layer of insulation increases the costs.
