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 …

Sands and mud are continually being transported around the world's coastal seas due to the
action of tides, wind and waves. The transport of these sediments modifies the boundary …

Detailed information on nearshore sediment transport processes during onshore bar
migration were obtained from large‐scale laboratory experiments with bichromatic wave …

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 …

Multi-frequency acoustics backscattering has been used for over a decade, to quantitatively
measure profiles of suspended sediment particle size and concentration, in the bottom 1–2m …

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 …

Above steep, wave‐induced sand ripples, which occur extensively in shallow sea areas, the
momentum transfer and suspended sediment dynamics are dominated by the formation and …

Ripples take time to evolve to a new equilibrium state in response to a change in wave‐
generated oscillatory flow. The paper presents results from flow tunnel experiments …

We have analysed the trajectories of small particles released into a turbulent flow over a
wavy wall in order to clarify the role of coherent structures in controlling the suspension and …

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 …
