Nivation

Today, Nivation is a topic that has captured the attention of a wide spectrum of society. Whether due to its impact on the industry, its relevance in popular culture, or its influence in the scientific field, Nivation has managed to cross the barriers of gender, age and nationality. In this article, we will explore the various facets of Nivation and its importance in the contemporary world. From its origin to its future projections, we will delve into a deep analysis that will allow us to better understand the relevance of Nivation in our current society.

Nivation is the set of geomorphic processes associated with snow patches. The primary processes are mass wasting and the freeze and thaw cycle,[1] in which fallen snow gets compacted into firn or névé. The importance of the processes covered by the term nivation with regard to the development of periglacial landscapes has been questioned by scholars, and the use of the term is discouraged.[2]

Nivation has come to include various subprocesses related to snow patches which may be immobile or semi-permanent. These sub-processes include erosion (if any) or initiation of erosion, weathering, and meltwater flow from beneath the snow patch.[3]

Weathered particles are moved downslope by creep, solifluction and rill wash.[1] Over time, this leads to the formation of nivation hollows which, when enlarged, can be the beginnings of a cirque.[1]
