Unified view of sediment transport by currents and waves. I: Initiation of motion, bed roughness, and bed-load transport
TL;DR: In this paper, the effect of fine silt on the bed composition and on initiation of motion (critical conditions) of sediment beds over the full range of conditions (silts to gravel) is discussed.

The predictability of cross-shore bed evolution of sandy beaches at the time scale of storms and seasons using process-based Profile models
L.C. van Rijn,Dirk-Jan Walstra,Bart T. Grasmeijer,James Sutherland,Shunqi Pan,Joan Pau Sierra +5 more
TL;DR: In this paper, the authors present information of coastal processes on these time scales and assess the predictive capabilities of Profile models with respect to hydrodynamics and morphodynamics at sandy beaches on the time scales of storms and seasons.
Journal ArticleDOI
On two-phase sediment transport: sheet flow of massive particles
TL;DR: In this paper, a model for concentrated sediment transport that is driven by strong, fully developed turbulent shear flows over a mobile bed is presented, where balance equations for the average mass, momentum and energy for the two phases are phrased in terms of concentration-weighted (Favre averaged) velocities.

Review of wave‐driven sediment resuspension and transport in estuaries
Malcolm O. Green,Giovanni Coco +1 more
TL;DR: A review of wave-driven sediment resuspension and transport in estuaries, including generation of bed shear stress by waves, initiation of sediment motion by waves and the ways waves modulate, add to, and interact with sediment transport driven by currents, can be found in this paper.

Modeling cross-shore sandbar behavior on the timescale of weeks
B.G. Ruessink,Yoshiaki Kuriyama,Ad Reniers,Ad Reniers,J.A. Roelvink,J.A. Roelvink,Dirk-Jan Walstra +6 more
TL;DR: In this paper, the authors compare predictions of a coupled, wave-averaged, cross-shore waves-currents-bathymetric evolution model to observations of onshore and offshore nearshore sandbar migration.

Formulas for Bed-Load transport
E. Meyer-Peter,R. Müller +1 more
TL;DR: In this article, an attempt is made to derive an empirical law of bed-load transport based on recent experimental data and the results and interpretation of tests already made known in former publications of the Laboratory for Hydraulic Research and Soil Mechanics at the Federal Institute of Technology, Zurich.

A monograph on sediment transport in alluvial streams
TL;DR: In this article, the authors proposed the principle of similarity for the prediction of stage-discharge relations in alluvial streams. But they did not consider the effect of the number of particles in the stream.

The flow of cohesionless grains in fluids
TL;DR: In this article, it was shown that if the bed is composed entirely of potentially mobile grains a stress-equilibrium relation at the bed surface can be defined whereby the magnitude of a certain "bed load" of grains in transit over unit bed area is given in terms of the applied tangential stress.
