Evolution of meanders, a complex morpho-dynamic process, has been the focus of research challenging river engineers for decades. The study replicates the natural evolution of meandering processes by coupling the Bank Erosion and Retreat Model (BERM, by Chen and Duan) with a nonlinear flow model (by Blanckaert and de Vriend). Distinguished from our previous meander evolution model which adopted the first-order analytical solution of flow field in a sine-generated channel (by Johannesson and Parker), the present model is applicable to any channel planforms and more suitable for moderately and strongly curved flows. The computed results demonstrate the improvement of simulation of meander evolution by adopting the advanced hydrodynamic model. |
