Iain S. Stewart Nivation Nivation morphogenetic term introduced by Matthes (
1900) to describe isa and explain the processes associated with latelying
seasonal snow patches and landforms derived from them (nivation benches or
terraces, ...

Mountains and Man: A Study of Process and Environment
NIVATION The presence of late-lying snow patches on mountain slopes may
contribute markedly to localized erosion through a number of related processes
known collectively as nivation. Nivation includes frost action, mass-wasting, rill
and ...

Geomorphology: Themes and Trends
Nivation hollows and other effects of nivation processes in Lappland The term
nivation was introduced by Matthes (1900) to indicate snow-patch erosion,
resulting from intensified frost-weathering, slope wash and mass movements of
debris ...

modic, site-specific and speculative. The uncritical regard with which some
researchers have viewed the erosive potential of nivation is evident in the
persistent attribution of large 'nivation cirques' to snowpatch erosion alone, even
though this ...

Wind as a Geomorphic Agent in Cold Climates
This process Matthes (1900) termed nivation, which is used to designate all
aspects of weathering and transport which are accelerated or intensified by the
presence of late-lying snow (Thorn 1979b: 41 ). Nivation means weathering and
...

Earth Environments: Past, Present and Future
The net effect of nivation is to produce a nivation hollow with the passage of time
and eventually a nivation cirque. Lewis (1939) believed that nivation processes
were an essential prerequisite for the development of true corrie landforms ...

Nivation landforms Nivation niches or nivation hollows develop in slopes
beneath a snow cover (Figure 8.27). The melt waters percolate through the
ground beneath and adjacent to the snow patches. When this water reaches the
freezing ...

Encyclopedia of Snow, Ice and Glaciers
Nivation operates in glaciated terrain, but it is not restricted to it. The main effect
of nivation is to create and remove fine sediments. Weathered particles are
moved downslope by creep, solifluction, and rill wash. Over time, this leads to the
...

Mountain Environments: An Examination of the Physical ...
This very brief review of nivation has shown that understanding of the processes
involved is rudimentary and an unambiguous definition of nivation impossible.
This reinforces Thorn's (1988) plea that nivation, as a term, should be abandoned
...

Geography: An Integrated Approach
Snow Snow is the agent of several processes which collectively are known as
nivation (page 111). These nivation processes, sometimes referred to as '
snowpatch erosion', are believed to be responsible for enlarging hollows on
hillsides.
