Abstract: A model has been developed for the prediction of the density functions of bed-elevation and entrainment and deposition rates of sediment in sand bed streams within the lower regime flow condition. The model incorporates ...

Abstract: A model was developed for the prediction of the density functions of entrainment and deposition rates of nonuniform sediment. The model incorporated both statistical and deterministic parameters in its formulation. The ...

Abstract: In this study, a bedload model for nonuniform sediment is developed considering the density function of sediment entrainment with no active layer. The model is formulated based on physical considerations, dimensional ...

Abstract: Density currents represent a broad class of flows driven by gravity acting on a density difference with the ambient environment. The understanding of the underlying mechanisms of density currents and their implications on ...

Abstract: Diverging channels, also known as diffusers, represent common natural and industrial outlets to lakes, reservoirs, and rivers. If the outflow in a diffuser has a larger density than the ambient water, the inflow may plunge ...

Abstract: A numerical model of turbidity currents with a deforming bottom boundary has been developed. The model predicts the vertical structure of the flow velocity and concentration as well as change in the bed level due to erosion ...

Abstract: A well-tested numerical model based on the Reynolds averaged Navier–Stokes equations with

Abstract: A three-dimensional numerical model

Abstract: This paper presents measurements of velocity profiles obtained from idealized dam-break experiments and results from numerical simulations of these experiments. Dam-break flows were generated in the laboratory by suddenly ...
