river banks are exposed to bank erosion and destruction. one of the river engineering goals is to provide human life requirements and reduce river danger. so spreading extent of this phenomenon, whose risk and other important factors must be recognized. using groins is one of the control ways that by accurate design and accurate performance, bank erosion control and field reclamation would be p...

The Haw River, a high order river in the southeastern United States, is characterized by severe bank erosion and geomorphic change from historical conditions of clear waters and connected floodplains. In 2014 it was named one of the 10 most threatened rivers in the United States by American Rivers. Like many developed areas, the region has a history of disturbance including extensive upland soi...

We evaluate links between climate and simulated river bank erosion for one of the world's largest rivers, the Mekong. We employ a process-based model to reconstruct multidecadal time series of bank erosion at study sites within the Mekong's two main hydrological response zones, defining a new parameter, accumulated excess runoff (AER), pertinent to bank erosion. We employ a hydrological model t...

Phosphorus loss from bank erosion was studied in the catchment of River Odense, a lowland Danish river basin, with the aim of testing the hypothesis of whether stream banks act as major diffuse phosphorus (P) sources at catchment scale. Furthermore, the study aimed at analyzing the impact of different factors influencing bank erosion and P loss such as stream order, anthropogenic disturbances, ...

river bank erosion can result in considerable riparian land loss and the delivery of large volumes of sediment to reaches downstream. consequently, the ability to predict the stability and failure geometry of eroding river banks is an important prerequisite for es-timating the rate of bank erosion and sediment yield associated with bank erosion. in this paper a new model capable of analyzing th...

Streambank erosion hazard analysis by BEHI method, case study: Sajadroud stream, Mazandaran province Extended Abstract Introduction River bank erosion is a complex natural process and plays an important role in the dynamic equilibrium of the river. The amount of river bank erosion affects the river plan, cross section and dimensions of the river and is the main factor controlling channel mig...

Detailed topographic data collected with an airborne laser scanner can help determine the extent of bank erosion and identify banks that are more vulnerable to bank collapse and thus require stabilization efforts. The Minnesota River which flows through a 95% agricultural watershed has been ranked among the top 20 most polluted rivers in the U.S. Greater than 50% of the sediment load carried by...

Riparian forest vegetation is widely believed to protect riverbanks from erosion, but few studies have quantified the effect of riparian vegetation removal on rates of river channel migration. Measured historical changes in a river channel centreline, combined with mapped changes in floodplain vegetation, provide an opportunity to test how riparian vegetation cover affects the erodibility of ri...

Extended abstract Introduction The vital need for river management is understood and predicts bank erosion processes. River bank erosion is one of the sediment major sources for many rivers across the world. Bank erosion is a key process in fluvial dynamics, affecting a wide range of physical, ecological and socio-economic issues in the fluvial environment. These include the establishm...
