Journal ArticleDOI
Computational Dam-Break Hydraulics over Erodible Sediment Bed
TL;DR: In this paper, a theoretical model is built upon the conservative laws of shallow water hydrodynamics, and a high-resolution numerical solution of the hyperbolic system is achieved using the total-variation-diminishing version of the second-order weighted average flux method in conjunction with the HLLC approximate Riemann solver and SUPERBEE limiter.
Journal ArticleDOI
Coupled and Decoupled Numerical Modeling of Flow and Morphological Evolution in Alluvial Rivers
TL;DR: In this article, the impacts of simplifications in the water-sediment mixture and global bed material continuity equations as well as of the asynchronous solution procedure for aggradation processes are investigated.
Journal ArticleDOI
Explicit Formulation of the Shields Diagram for Incipient Motion of Sediment
TL;DR: In this paper, the authors developed an explicit formulation of the Shields diagram, enabling the critical Shields parameter to be determined directly from fluid and sediment characteristics without resorting to any trial and error procedure or iteration.
Journal ArticleDOI

TL;DR: In this article, the results of a benchmark test launched within the framework of the NSF-PIRE project "Modeling of Flood Hazards and Geomorphic Impacts of Levee Breach and Dam Failure" are presented.
Journal ArticleDOI
Turbulent Bursting-Based Sediment Entrainment Function
TL;DR: In this paper, a simple theoretical model for sediment entrainment from flat, loose bed is established using the averaged bursting period scaled on inner variables and the spatial scales of turbulent bursts.
