The river’s Geomorphology and its evaluation explore explanation of erosion, the longitudinal profile of the river bed and different forms of the rivers. Alvand River as the main river of the Alvand basin is located in Kermanshah Province W, Iran. The aim of this study is to investigate changes in longitudinal and longitudinal profiles of the river bed using mathematical functions and their rel...

  The natural environment has performed as determinative factor for vitality of the human habitations since the dawn of era, like habitations’ places and other human foundations which have been absolutely influenced by natural factors particularly geomorphological and geological factors. Geomorphological studies will evaluate environmental conditions of the chronological settlement ...

Terrain surfaces conserve human activities in terms of textures and structures. The objective of geomorphological filters is to distinguish between anthropogenically undisturbed and disturbed surfaces. Filters applied over high-resolution DTM show a clear anthropogenic character of contour lines and channels. Based on methodology of geomorphometry and geo-statistics a series of analyses functio...

Definition Geomorphology is the science that studies the origin and development of landforms and how those landforms combine to form landscapes. Landforms are shaped by geomorphological processes, many of which involve the weathering, erosion, transportation, and deposition of surface materials (rock, sediment) by gravity, ice, wind, or water. Both erosional and depositional landforms can be id...

A 0.9 km-reach of Uvas Creek, California, was reconstructed as a sinuous, meandering channel in November 1995. In February 1996, this new channel washed out. We reviewed project documents to determine the basis for the project design and conducted our own historical geomorphological study to understand the processes operating in the catchment and project reach. The project was designed using a ...
