Theory of river meanders

A mathematical model is developed for the calculation of flow field and bed topography in curved channels with an erodible bed. A small perturbation approach is used to linearize the governing equations. The downstream convective acceleration of the secondary flow is shown to give rise to a phase lag between secondary flow and channel centerline...

Computer simulated migration of meandering rivers in Minnesota

In the present work, a computer model for simulation of the migration of meandering rivers, developed by Beck [1985a], was applied to four rivers in the State of Minnesota. The computer model is based on a theoretical approach developed by Ikeda, Parker, and Sawai [1981]. The major objective was to evaluate the overall performance of the...
