Meander migration with physically-based bank erosion
Interest in meander evolution has recently been revitalized with ongoing efforts worldwide to re-naturalize highly modified streams through re-meandering, with the consequent need of assessment tools. While research on meandering rivers has been very productive in the last five decades, among the …

Channel-forming discharge and river meander migration modeling of the Pilcomayo River in the area of Misión La Paz (Argentina) and Pozo Hondo (Paraguay)
… understand the river's morphodynamics, RVR Meander, a 2D depth-averaged analytical model, was used to assess the channel's planform evolution in time. The model uses a single discharge value for the simulations, thus estimation of a channel-forming discharge was necessary for the model …

Curvature-Migration Relations and Planform Dynamics of Meandering Rivers
… advancing knowledge of the planform dynamics of meandering rivers. The intellectual merit of the research is the identification of the role of the spatial structure of planform curvature in the dynamics of meander migration. The new knowledge gained from the research provides an improved …

Numerical modeling of river migration incorporating erosional and depositional bank processes
… the nature of morphologic changes of meandering rivers has long attracted the attention of the scientific community, in the fields of fluvial geomorphology, hydraulic engineering and river restoration. Several meander evolution models developed over the years have provided a deeper …

Meandering river dynamics
Meandering channels are dynamic landforms that arise as a result of fluid mechanic and sedimentary processes. Their evolution has been described by the meander morphodynamic equations, which dictate that channel curvature and bed topology give rise to local perturbations in streamwise fluid …

River channel dynamics mapped with dense lidar point cloud time series
… alluvial channel bends to migrate laterally, or meander, resulting in dynamic topographic changes observable over human time scales. The beauty and ubiquity of the patterns created by meander migration—as well as the consequences of rapid channel movement for river-adjacent communities—have led …
