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 …

The knowledge and modeling of wave‐induced sand transport over rippled beds still has
significant shortcomings, which is partly related to a lack of measurements of the detailed …

New large-scale experiments have been carried out in two oscillatory flow tunnels to study
ripple regime sand suspension and net sand transport processes in full-scale oscillatory …

The present study focuses on the fine‐scale flow and sand transport processes above
onshore migrating ripples below skewed surface gravity waves in the shoaling zone. A set of …

A large series of field-scale experiments on turbulent sand-laden flows, conducted in
preceding years in the LOWT and AOFT large oscillating water tunnels are reviewed and …

Many existing practical sand transport formulae for the coastal marine environment are
restricted to a limited range of hydrodynamic and sand conditions. This paper presents a …

Acoustic measurements of near‐bed sediment diffusivity profiles are reported. The
observations were made over two sandy rippled beds, classified as “medium” and “fine” in …

Large‐scale wave flume experiments are conducted in the ripple vortex regime to study near
bed coarse sand transport processes below asymmetric surface waves typical of the coastal …

A direct numerical simulation study is conducted to investigate sinusoidal oscillatory flow
over a two-dimensional wavy wall. The height and wavelength of the bottom profile, and the …

In shallow coastal regions, shoaling waves and current together determine the net sediment
transport rate, Q net, which is critical for understanding coastal morphodynamics. Moderate …
