Brief life of William Morris Davis, pioneering geomorphologist. western United States, he devised the theory for which he is best known: the “Erosional Cycle.

The geographical cycle of erosion as envisaged by Davis is a geographical model and an early paradigm in geomorphology. His work has proved to be a simple and effective vehicle for teaching, and it had a profound effect on the development of geomorphology in the English speaking world.

Davis’ Stages in the fluvial cycle of erosion published in 1909 defined a young, mature, and old sequence in the development of river valleys and the landscape the rivers were eroding. The geographical cycle of erosion as envisaged by Davis is a geographical model and an early paradigm in geomorphology. His work has proved to be a simple and effective vehicle for teaching, and it had a profound effect on the development of geomorphology in the English speaking world. From a theoretical perspective, under the conditions Davis specified (an episode of uplift followed by a long period of no further uplift, erosion dominated by fluvial processes, and no major sea-level, climate or tectonic change), the postulated cycle of erosion is exactly what would happen, as physical models testify. Davisian cycle (cycle of erosion) Orderly series of stages through which land-forms were believed to pass from their initiation following uplift to their final planation by erosion. The cycle of erosion, as envisioned by Davis, has its initial stage at a time when the landmass is rapidly elevated by internal earth forces, followed by a very long period of tectonic quiescence.

Davis conceived the cycle of erosion model in the 1880s. More fully developed by 1900 it received wide acclaim, but was never universally accepted. The initial enthusiasm and strength of the cycle of erosion model has been attributed to various causes.
