Abstract. Hydraulic models are often employed to predict the response of a stream to a proposed restoration design. The shortfall of many currently used models is that they only look at the site where stabilization will occur without considering upstream and downstream effects. The one-dimensional (1D) computer model Conservational Channel Evolution and Pollutant Transport System (CONCEPTS) addresses this shortcoming by modeling streambank stabilization on a reach scale. The capability of this… 
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
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


Modeling the Evolution of Incised Streams. II: Streambank Erosion
Incision and ensuing widening of alluvial stream channels is widespread in the midsouth and midwestern United States and represents an important form of channel adjustment. Streambanks have been
Discussion of “Modeling the Evolution of Incised Streams. II: Streambank Erosion” by Eddy J. Langendoen and Andrew Simon
The authors are to be congratulated on having successfully implemented a conceptual model for two bank failure mechanisms into their numerical model CONservational Channel Evolution and Pollutant
Disturbance, stream incision, and channel evolution: The roles of excess transport capacity and boundary materials in controlling channel response
Abstract Channel incision is part of denudation, drainage-network development, and landscape evolution. Rejuvenation of fluvial networks by channel incision often leads to further network development
Evaluation of the Bank Stability and Toe Erosion Model (BSTEM) for Predicting Lateral Streambank Retreat on Ozark Streams
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 by the USDA-ARS National Sedimentation Laboratory in
Subsurface transport of phosphorus in riparian floodplains: influence of preferential flow paths.
The potential for nutrient subsurface transport shown by this alluvial system has implications regarding management of similar riparian floodplain systems.
A simplified 2D model for meander migration with physically-based bank evolution
Abstract The rate of migration, calculated by numerical models of river meandering, is commonly based on a method that relates the rate of migration to near-bank excess velocity multiplied by a
Quantification and Heterogeneity of Infiltration and Transport in Alluvial Floodplains
In order to protect drinking water systems and aquatic ecosystems, all critical nutrient source areas and transport mechanisms need to be characterized. It is hypothesized that hydrologic
A model of channel response in disturbed alluvial channels
Dredging and straightening of alluvial channels between 1959 and 1978 in West Tennessee caused a series of morphologic changes along modified reaches and tributary streams. Degradation occurred for
Numerical simulation of hydrodynamics and bank erosion in a river bend
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
The Role of Subsurface Flow in Hillslope and Stream Bank Erosion: A Review
Sediment is one of the most common causes of stream impairment. Great progress has been made in understanding the processes of soil erosion due to surface runoff and incorporating these in prediction
