Global climate change has been projected to affect hydrology, the ice-covered flow period and river morphology (including changed sediment transport conditions) in northern high-latitude regions. To understand impact of expected shortening on bedload transport, one needs present these rivers with annually occurring ice cover. Thus, aims are (1) define impacts cover near-bed characteristics duri...
Local scour around piers is the major cause of their foundation failure in the river bends that endangers the stability of the structure and its efficiency. Riprap is commonly placed around the bridges piers for local scour protection. The aim of this study was to present an equation for estimating stable riprap diameter around a cylindrical bridge pier in river bends. In this study, using an e...
The present paper tries to describe the advantage and improvement of a numerical model when predicting government processes on Flow Rivers. With regard to the important effect of the flow velocity and shear stress forces on river bank erosion, we apply a Two-Dimensional numerical model, named CCHE2D, to simulate river flow pattern at a meandering river Khoshk-e-Rud River of Farsan, 30 Km west o...
During times of lowered sea level, Mekong River and Red incised valleys into the ancient coastal plains exposed shelves western South China Sea. The deglacial fill history valley was investigated by seismic surveys sediment cores. channels mainly exhibit a low-sinuosity course, but some channel segments are bent. oldest part channel-bend exhibits shingled reflectors in Parasound records documen...
An abandoned stream valley, here called Florence Valley, was found in eastern Erie County, Ohio. Florence Valley is about one mile long and connects the valleys of Chappel Creek and the Vermilion River. There is evidence that Florence Valley was formed as a result of the capture of a tributary of the Vermilion River by Chappel Creek. Chappel Creek, at the junction of Florence Valley and the val...
