RISSimulation-Based Approach for Stream Restoration Structure Design: Model Development and Validation
Publisher: American Society of Civil Engineers
Abstract: We develop, validate, and demonstrate the potential of Virtual StreamLab (VSL3D), a novel three-dimensional hydromorphodynamics computational model capable of simulating turbulent flow and sediment transport in natural ...
Effect of Inlet Turbulent Boundary Conditions on Scour Predictions of Coupled LES and Morphodynamics in a Field-Scale River: Bankfull Flow Conditions
Publisher: ASCE
Abstract: This paper presents a systematic numerical investigation to study the effects of inlet turbulent boundary conditions on the coupled hydrodynamics and morphodynamics computations of a natural river, the Feather River, located ...
3D Numerical Modeling of Flow and Sediment Transport in Laboratory Channel Bends
Publisher: American Society of Civil Engineers
Abstract: The development of a fully three-dimensional finite volume morphodynamic model, for simulating fluid and sediment transport in curved open channels with rigid walls, is described. For flow field simulation, the Reynolds-averaged ...
Comparative Hydrodynamic Study of Rigid-Lid and Level-Set Methods for LES of Open-Channel Flow
Publisher: American Society of Civil Engineers
Abstract: Computational modeling of open-channel flows at low Froude (F) numbers is often carried out using the rigid-lid assumption to prescribe the water surface location. However, the presence of wall-mounted hydraulic structures ...
