Understanding how hydraulic factors control alluvial river meander migration can help resource managers evaluate the long-term effects of floodplain management and bank stabilization measures. Using a numerical model based on the mechanics of flow and sediment transport in curved river channels, we predict 50 years of channel migration and suggest the planning and ecological implications of tha...

application of structures of flow pattern modification is one of the erosion control methods in bends. triangular vanes are among these structures which provide less scour depth compared to the other techniques such as spur dike. since little information on erosion and sedimentation pattern around triangular vanes are available, this study was conducted to study the effect of structure effectiv...

In China, the Lower Jingjiang Reach (LJR) of the Yangtze River could be one of the most complicated areas in terms of channel migration. The river had undergone many channel changes in the reach since the 18th century. Intensive human activities in recent decades, such as the construction of upstream dams and revetments, had directly affected the channel migration characteristics. The revetment...

Among the various hazards created by nature on the earth’s surface, the one caused by flood and river bank erosion is more common and quite devastating. Like, earthquake and volcanic eruptions, it also affects human activities in various ways wherever it occurs. Erosion, transportation and deposition are the main functions of a river. Through these activities, it creates different landforms and...

The authors present an assessment of risk from river bank erosion in the Brahmaputra river basin. The concept of risk is conceptualised in the context of socio-economic vulnerability, and the potential for exposure to hazard. By addressing both the physical hazard and the variations across the socio-economic surface the approach presented attempts to spatially combine these parameters to provid...

Thousands of stream miles in the southern Piedmont region are impaired because of high levels of suspended sediment. It is unclear if the source is upland erosion from agricultural sources or bank erosion of historic sediment deposited in the flood plains between 1830 and 1930 when cotton farming was extensive. The objective of this study was to determine the source of high stream suspended sed...
