Abstract
An updated computer model for meandering rivers has been developed using the Linearization Analyses of Johannesson and Parker (1989) and Sun et al. (2001a, b). The model simulates the bed topography, flow field, and bank erosion rate in a curved channel with an erodible bed. Sediment mass balance is preserved and to update the channel bed elevation, which is represented by a 2D cell with high elevation area, water surface elevation area, and low elevation area. The model is used to simulate a laboratory channel migration where the upstream channel migration is slowed down due to channel erosion and high bank height.
