Bank and near-bank processes in an incised channel
TL;DR: In this paper, the authors investigated the role of matric suction, positive pore-water pressure and confining pressure for layered streambanks composed of cohesive materials in determining bank strength.

Numerical simulation of hydrodynamics and bank erosion in a river bend
Abstract: We present an integrated analysis of bank erosion in a high-curvature bend of the gravel bed Cecina River (central Italy). Our analysis combines a model of fluvial bank erosion with groundwater flow and bank stability analyses to account for the influence of hydraulic erosion on mass failure processes, the key novel aspect being that the fluvial erosion model is parameterized using outputs from detailed hydrodynamic simulations. The results identify two mechanisms that explain how most bank retreat usually occurs after, rather than during, flood peaks. First, in the high curvature bend investigated here the maximum flow velocity core migrates away from the outer bank as flow discharge increases, reducing sidewall boundary shear stress and fluvial erosion at peak flow stages. Second, bank failure episodes are triggered by combinations of pore water and hydrostatic confining pressures induced in the period between the drawdown and rising phases of multipeaked flow events.

Numerical simulation of bank erosion and channel migration in meandering rivers
TL;DR: In this article, a numerical model of river morphology for meander bends with erodible cohesive banks was developed and tested, where the governing conservation equations were implemented in a moving boundary fitted coordinate system that can be both curvilinear and nonorthogonal.
