Desert geomorphology or the geomorphology of arid and semi-arid lands shares many landforms and processes with more humid regions. One distinctive feature is the sparse or lacking vegetation cover, which influences fluvial and slope processes, related to wind and salt activity. [4]
[5] [6] Although the field of biogeomorphology had not yet been named, Darwin's work represents the earliest examination of a faunal organism influencing landscape process and form. [6] Charles Darwin begins his work on worms with an examination of behavior and physiology, which then moves towards topics related to geomorphology, pedogenesis ...
It is a response to the development of this GIS technology to gather and process DEM data (e.g. remote sensing, the Landsat program and photogrammetry). Recent applications proceed with the integration of geomorphometry with digital image analysis variables obtained by aerial and satellite remote sensing . [ 7 ]
An early popular geomorphic model was the geographical cycle or cycle of erosion model of broad-scale landscape evolution developed by William Morris Davis between 1884 and 1899. [11] It was an elaboration of the uniformitarianism theory that had first been proposed by James Hutton (1726–1797). [24]
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.
Mass wasting is a general term for any process of erosion that is driven by gravity and in which the transported soil and rock is not entrained in a moving medium, such as water, wind, or ice. [2] The presence of water usually aids mass wasting, but the water is not abundant enough to be regarded as a transporting medium.
The geographic cycle, or cycle of erosion, is an idealized model that explains the development of relief in landscapes. [1] The model starts with the erosion that follows uplift of land above a base level and ends, if conditions allow, in the formation of a peneplain. [1]
At a glimpse in geologic time, one of these forcing mechanisms may look to be the dominant process. Observations made on long geologic times scales (≥10 6 annum ) typically reveal much about slower, larger-magnitude geologic processes such as tectonism [ 5 ] from a regional to even global scale.
