Modeling morphodynamic processes in meandering rivers with spatial width variations

G Zolezzi, R Luchi, M Tubino - Reviews of Geophysics, 2012 - Wiley Online Library
Most morphodynamic models of river meandering assume spatially constant width;
depending on the intensity of spatial width variations, different meandering styles actually …

A new framework for modeling the migration of meandering rivers

G Parker, Y Shimizu, GV Wilkerson… - Earth Surface …, 2011 - Wiley Online Library
Many models of river meander migration rely upon a simple formalism, whereby the eroding
bank is cut back at a rate that is dictated by the flow, and the depositing bank then migrates …

[图书][B] Rivers in the Landscape

E Wohl - 2020 - books.google.com
Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea
level do not lie within a drainage basin. Even points distant from the nearest channel are …

A simplified 2D model for meander migration with physically-based bank evolution

D Motta, JD Abad, EJ Langendoen, MH Garcia - Geomorphology, 2012 - Elsevier
The rate of migration, calculated by numerical models of river meandering, is commonly
