AbstractCohesive sediment detachment is typically modeled for channels, levees, spillways, earthen dams, and internal erosion by using a linear excess shear stress approach. However, mechanistic nonlinear detachment models, such as the Wilson model, have recently been proposed in the literature. Questions exist as to the appropriateness of nonlinear relationships between applied shear stress and the erosion rate. Therefore, the objective of this research was to test the appropriateness of… 
Watershed Variability in Streambank Erodibility and Implications for Erosion Prediction
Two fluvial erosion models are commonly used to simulate the erosion rate of cohesive soils: the empirical excess shear stress model and the mechanistic Wilson model. Both models include two soil
Quantifying Sediment Loads from Streambank Erosion and Potential Load Reductions from Streambank Stabilization Using Process-based Modeling
Unstable streambanks contribute a significant sediment load to surface waters in some watersheds. Streambank stabilization techniques are available to increase stability of streambanks or reduce
Sediment detachment and transport processes associated with internal erosion of soil pipes
Subsurface flow can be an important process in gully erosion through its impact on decreasing soil cohesion and erosion resistance as soil water content or pressure increases and more directly by the
Evaluating a process‐based model for use in streambank stabilization: insights on the Bank Stability and Toe Erosion Model (BSTEM)
Streambank retreat is a complex cyclical process involving subaerial processes, fluvial erosion, seepage erosion, and geotechnical failures and is driven by several soil properties that themselves
Major advances in the modeling of dam breach processes have occurred as a result of improved methods for quantifying erosion resistance of embankment materials through field and laboratory testing.
