A heated sidewalk in Holland, Michigan Installation of a geothermal snowmelt system on a street in Reykjavík, Iceland.. A snowmelt system prevents the build-up of snow and ice on cycleways, walkways, patios and roadways, or more economically, only a portion of the area such as a pair of 2-foot (0.61 m)-wide tire tracks on a driveway or a 3-foot (0.91 m) center portion of a sidewalk, etc.
Where solar radiation is the dominant cause of snow ablation (e.g., if air temperatures are low under clear skies), characteristic ablation textures such as suncups and penitentes may develop on the snow surface. [6] Ablation can refer to mass loss from the upper surface of a glacier or ocean-driven melt and calving on the face of a glacier ...
De-icing is defined as removal of existing snow, ice or frost from a roadway, airport runway, roof, or other surface. It includes both mechanical means, such as plowing, vacuuming or scraping, and chemical means, such as application of salt or other ice-melting chemicals.

The snow does not melt slower gradually with distance from the trunk, but rather creates a wall surrounding snow-free ground around it. According to some of sources, North American spring ephermal plants like spring beauty ( Claytonia caroliniana ), trout lily ( Erythronium americanum ) and red trillium ( Trillium erectum L.) benefit from such ...

Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
Snow hydrology is a scientific study in the field of hydrology which focuses on the composition, dispersion, and movement of snow and ice.Studies of snow hydrology predate the Anno Domini era, although major breakthroughs were not made until the mid eighteenth century.
To improve traction and melt ice or snow, winter service vehicles spread granular or liquid ice-melting chemicals and grit, such as sand or gravel. The most common chemical is rock salt, which can melt snow at high temperatures but has some unwanted side effects.
