Concept of Cycle of Erosion

Understanding the Stages of Fluvial Erosion

Abstract

The idea of cycle of erosion was figured by William Morris Davis, an American geomorphologist, towards the finish of the nineteenth century. It is an idea of a precise succession of evolu­tionary phases of fluvial erosion in which alleviation of the accessible landmass decreases with time to arrive at a late stage when the landscape turns into a peneplain. The cycle of erosion, as imagined by Davis, has its underlying stage when the landmass is quickly raised by inner earth powers, trailed by a long time of structural quies­cence. When raised high above ocean level as a landmass, streams appear and erosion starts to work on the elevated mass which is progressively worn out nearly to a plain. The landmass may, at some later time, be restored and the cycle starts again and remainders of the prior cycle of erosion are safeguarded at new and more significant levels.
