Approaches to Modeling Width Adjustment in Curved Alluvial Channels
1993
Darby, Stephen E. | Thorne, Colin R.
The application of many existing numerical models of river channel morphology is limited by their inability to account for bank erosion and changing channel width. In this report, methods of numerically modelling river channel width adjustment in curved streams are investigated in order to determine the feasibility of developing an effective, rational method for predicting dynamic river channel response to modification in control variables. The main scope of the report is concerned with seeking approaches to modelling width adjustment in relatively large, sand-bed, curved alluvial channels with cohesive bank material, though an approach for modelling width adjustment in non-cohesive channels is also outlined.
