erosion cycle

erosion cycle

[ə′rō·zhən ‚sī·kəl]
(geology)
A postulated sequence of conditions through which a new landmass proceeds as it wears down, classically the concept of youth, maturity, and old age, as stated by W.M. Davis; an original landmass is uplifted above base level, cut by canyons, gradually converted into steep hills and wide valleys, and is finally reduced to a flat lowland at or near base level.

Hence, in an attempt to achieve a new morphological balance, another erosion cycle begins with the verticalization of the riverbanks leading to significant erosion rates in the period of july to september, but at levels well below the previous period; nevertheless, river discharges in a regulated pattern are driven by the operation of the dams for power generation.
