How do different theories of landform development explain changes in the fluvial landscape?
There are various theories that explain the development of the landforms, such as the William Morris Davis theory. The theory explains the development of the landforms through the concept of the geomorphic cycle.
It provides a genetic classification and a systemic description of landforms. According to Davis, the cycle is a period when the landmasses got uplifted and later on the landscape undergoes transformation to a low featureless peneplain.
Another theory of landforms development was given by Wiliam Walter Penck, the characters of landforms of a given place are related to the tectonic activity of the region.
As contrary to the concept the landscape is a product of the structure, process, and stage. Thereof upliftment is in relation to the degradation where it assumed that the interaction between the upliftment and degradation are continuous.
The theory of G.Karl Gilbert associated the development of the landforms to be in relation to the dynamic equilibrium theory. It involves the time-independent development of the landforms and it became subsequent Important in drastic methodological shifts in geomorphology. According to his landforms is a result of the tendency towards variability and tendency towards uniformity.
The next theory is put forward by L.C King, landforms development in arid and semi-arid regions of Savanna in south Africa. He formulated the cyclic models such as hillslope cycle, pediplaination, and epigenetic cycles. The development of the hillslopes in all regions and in all climates sufficient relief and Fluvial process are the dominant factors of denudation.
