Modeling of multilayer cohesive bank erosion with a coupled bank stability and mobile-bed model (2014)
Journal Article
Lai, Y. G., Thomas, R. E., Ozeren, Y., Simon, A., Greimann, B. P., & Wu, K. (2015). Modeling of multilayer cohesive bank erosion with a coupled bank stability and mobile-bed model. Geomorphology, 243, 116-129. https://doi.org/10.1016/j.geomorph.2014.07.017

Streambank erosion can be an important form of channel change in unstable alluvial environments. It should be accounted for in geomorphic studies, river restoration, dam removal, and channel maintenance projects. Recently, one-dimensional and two-dim...

CRC Press. https://doi.org/10.1201/b16630-10

The previous chapter outlined the challenges of looking after plants and animals hydraulic experiments. These challenges can be circumvented if inanimate surrogates can be substituted for the prototype organisms without detriment to the relevance of...

Aquatic vegetation interacts with the flow by posing an obstruction and in return experiences drag and is reconfigured by acting forces. It is suggested that plant buoyancy and stiffness affect these bio-physical interactions and hence should be cons...
