This vision paper discusses the advances made over the last three decades in coastal sand
transport and morphodynamics, and the research needs for the coming decades. The prime …

Sand transport and morphological change occur in the wave bottom boundary layer due to
sand particle interactions with an oscillatory flow and granular interactions between …

Bed load transport over ripples and dunes in rivers exhibits strong spatial and temporal
variability due to the complex turbulence field caused by flow separation at bedform crests. A …

The paper presents a numerical movable-bed channel capable of simulating three-
dimensional motions of flows and gravel particles in different shapes. At first, the numerical …

The evolution of ripple geometries and their equilibrium states due to different wave forcing
parameters are investigated by a Reynolds‐averaged two‐phase model, SedFoam, in a two …

We describe an oscillating boundary layer apparatus (OBLA) to investigate mass and
momentum transfer in the wave bottom boundary layer. The facility is designed such that …

Characterizing the interaction of mobile sediments with a turbulent boundary layer driven by
waves and currents represents an important scientific and engineering challenge. To …

Direct numerical simulations of oscillatory flow over a bed made of ripples have been
performed. Two oscillatory flow forcing mechanisms have been compared:(i) a sinusoidal …

A two-dimensional, two-phase flow model is applied to the study of sediment motion over
vortex ripples under oscillatory flow conditions. The Reynolds-averaged continuity equations …
