Snowpack

Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude.[1][2] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding. Snowpacks provide water to down-slope communities for drinking and agriculture.[3] High-latitude or high-elevation snowpacks contribute mass to glaciers in their accumulation zones, where annual snow deposition exceeds annual melting.[4]

Assessing the formation and stability of snowpacks is important in the study and prediction of

hydrometeor[11] and on the ground.[12]

Scientific applications

Snowpack modeling is done for snow stability, flood forecasting, water resource management, and climate studies.[13] Snowpack modeling is either done by simple, statistical methods such as degree day or complex, physically based energy balance models such as SNOWPACK, CROCUS or SNOWMODEL.[14][15]
