Snowpack forms from layers of
snow that accumulate in geographic regions and high elevations where the climate includes cold weather for extended periods during the year. Snowpacks are an important water resource that feed streams and rivers as they melt. Therefore, snowpacks are both the drinking water source for many communities and a potential source of flooding (in case of sudden melting). Snowpacks also contribute mass to
glaciers in their
accumulation zone.
Assessing the formation and stability of snowpacks is important in the study and prediction of
avalanches. Scientists study the physical properties of snow under different conditions and their evolution, and more specifically snow
metamorphism, snow
hydrology (that is, the contribution of snow melt to
catchment hydrology), the evolution of snow cover with
climate change and its effect on the
ice–albedo feedback and hydrology, both on the ground and by using
remote sensing. Snow is also studied in a more global context of impact on animal
habitats and
plant succession.
An important effort is put into snow classification, both as a
hydrometeor and on the ground.
Scientific applications

Snowpack modeling is done for snow stability, flood forecasting, water resource management, and climate studies.
Snowpack modeling is either done by simple, statistical methods such as
degree day or complex, physically based energy balance models such as the SNOWPACK model, the CROCUS model or SNOWMODEL.
