Meander Flow Model. II: Applications

Abstract

An analytical model for simulating the flow and bed topography in a meandering alluvial channel is tested with data from two field studies. One set of data is used for testing a technique which involves discretizing the river channel into a number of straight and constant‐radius reaches, and solving a set of governing equations for each reach, using appropriate boundary conditions. The other set of data is used for testing a solution for a sequence of sine generated meander curves. In both cases the simulated flow and bed features are in good agreement with those measured. The agreement is obtained without use of calibration factors. With its ability to predict both magnitude and location of bed scour near outer banks in meander curves, the model should be a useful tool for the design of bank‐protection structures.
