In the last two-three decades the majority of Czech geographers and geomorphologists is taking a negative standpoint towards the theory of the geomorphologicalcycle of W. M. Davis. The present article shows their unfavourable impact
On depositional cycles and geomorphological development of the Han River Delta of South China in Coasts : erosion and sedimentation.
This paper has three objectives : to analyze the depositional cycles and features of the delta| to discuss the geomorphological characteristics and to describe the landform types| to give a discussion about the developmental process and mode

This paper provides an evolution of geomorphological surfaces effected by plate tectonic, erosion and accumulation in the Carpathian Basin. The basis of the study is a model for the geomorphologic evolution of the Transdanubian Mountains, North
geomorphology plays a key role: (1) links between topography, tectonics, and atmospheric circulation; (2) links between geomorphic processes and biogeochemical cycles; and (3) links between biological processes and the Earth’s surface. In conclusion, key
The aim of this review is to introduce some key examples showing the role of Earth surface processes, the traditional subject of geomorphology, within the interacting Earth system. The paper considers three examples of environmental systems in which
Though climatic geomorphology has long been perceived as providing a realistic framework for landform analysis, only the arid , nival and glacial systems and some constructional forms on the coast are readily identified in the landscape, present
Fewer freeze-thaw cycles were recorded in the air than at 1 and 3.5 cm in the bedrock, between December 1983 and April 1984. The number of cycles that could be declared geomorphologically effective according to established temperature criteria
was normally less than half the total number of freeze - thaw cycles recorded in both air and bedrock. Under the current temperature regime at the field site, few effective cycles are capable of penetrating more than 5 cm into the free face.
The purpose of this paper is to discuss and illustrate, by means of a few examples, how classical equilibrium concepts in geomorphology relate to the analysis of systems and to point out the limits these classical equilibrium concepts impose on our

The purpose of this paper is to historiographically analyze early literature enunciating the systematic-process paradigm in geomorphology, with particular emphasis on notions concerning Gilbert and systems.

Consideration of the 14,250 km2 of the Maryland and Pennsylvania Piedmont at six different periods of time from the Permian to the Holocene demonstrates that at least three cycles of tectonism/erosion have affected the Piedmont landscape. Each

The Cycle of Erosion formulated by the American geographer W.M. Davis in 1880s remained the dominant paradigm in geomorphology well into the 20th century, before it waned in response to improved understanding of Earth's crustal and surface behavior
