because it is not possible to recognize the mechanism of cantilever failure in field studies, this type of common failure in riverbanks is investigated in the laboratory. for this purpose, two samples of susceptible soil that forms an overhanging block in riverbanks are used for physical model tests to determine their physical, chemical and mechanical characteristics. soil blocks of different d...

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...

Streambank erosion is known to be a major source of sediment in streams and rivers. The Bank Stability and Toe Erosion Model (BSTEM) was developed in order to predict streambank retreat due to both fluvial erosion and geotechnical failure. However, few, if any, model evaluations using long-term streambank retreat data have been performed. The objectives of this research were to (1) monitor long...

Coupled two-dimensional (2D) morphodynamic and bank erosion models are gaining attentions in recent years. It has been shown that such models have advantages over the one-dimensional (1D) modeling approaches. In this paper, a previous 2D bank erosion model with the moving mesh method is extended to include the fixed mesh approach. Further, two practical streams with differing complexity are sim...

Bank retreat plays a fundamental role in fluvial and estuarine dynamics. It affects the cross-sectional evolution of channels, provides source sediment, modulates diversity habitats. Understanding predicting geomorphological response fluvial/tidal channels to external driving forces underpins robust management water courses protection wetlands. Here, we review bank with respect mechanisms, obse...

Japanese banks are among the world’s largest global financial intermediaries, with a significant presence in many regions, particularly the United States and Southeast Asia. In addition to being among the world’s largest banks, they have some of the world’s largest problems. Recent studies have found that Japanese banks have reduced lending as a consequence of these problems, that this shrinkag...

The Itaipu reservoir was created in 1984 on the Parana River, Paraguay-Brazil border. is 181 km long, 7 mean width, its capacity exceeds 29.109 m3 and bank line has over 2,919 km. objective of present work to estimate magnitude shoreline recession rates Brazilian shorelines since formation (1984) 2016, through cartographic sources (1984-1992), direct field measurement adopting erosion pins tech...

Burrowing into riverbanks by animals transfers sediment directly river channels and has been hypothesised to accelerate bank erosion promote mass failure. A field monitoring study on two UK rivers invaded signal crayfish (Pacifastacus leniusculus) assessed the impact of burrowing processes. Erosion pins were installed in 17 across a gradient burrow densities monitored for 22 months. Bank retrea...
