|Abstract: ||Numerical simulation of flows, sediment transport and river channel change in complex geometries of natural environment is a challenge to computational fluid dynamics (CFD). The difficulties include not only the discretization of the physical domain with a computational mesh, but also the capabilities of simulating the short and long term channel morphologic change in response to adjustment of hydraulic structures. Therefore, a robust numerical modeling system consisting of an efficient mesh generator and fluvial process simulator is needed.
In this study, the response of the Arkansas River navigation channel to riverine structure modifications was simulated by using a hydrodynamic and sediment transport computational model, CCHE2D. The feasibility of deepening the channel using modified dike fields with more, higher and longer dikes was confirmed with this model. In addition, the new design of the dike fields was further improved by multiple simulations of the computational model.|
