Sensitivity Analysis and Statistical Convergence of a Saltating Particle Model
Publisher: American Society of Civil Engineers
Abstract: Saltation models provide considerable insight into near-bed sediment transport. This paper outlines a simple, efficient numerical model of stochastic saltation, which is validated against previously published experimental ...
Godunov-Type Solution of Curvilinear Shallow-Water Equations
Publisher: American Society of Civil Engineers
Abstract: This paper presents details of a second-order accurate Godunov-type numerical model of the two-dimensional conservative hyperbolic shallow-water equations written in a nonorthogonal curvilinear matrix form and discretized ...
Characteristics of Hyperconcentrated Sediment-Laden Flows
Publisher: American Society of Civil Engineers
Abstract: Microscopic and macroscopic characteristics of hyperconcentrated sediment-laden flows are investigated using kinetic theory for differing concentrations of non-cohesive sediment particles. Variations in the microscopic ...
Run-Up of Solitary Waves on Twin Conical Islands Using a Boussinesq Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the interaction of solitary waves (representative of tsunamis) with idealized flat-topped conical islands. The investigation is based on simulations produced by a numerical ...
Double Layer–Averaged Model of River Ice–Water Mixture Flow
Publisher: American Society of Civil Engineers
Abstract: River ice–water mixture flows are commonly occurring natural phenomena that have the potential to cause serious hazards. To date, however, the interactive processes between ice and water have remained poorly understood. ...
