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 …

Combined-flows, which involve a combination of unidirectional and wave-induced
oscillatory flow, are omnipresent in coastal and lacustrine environments. Despite the …

The ability to predict the presence and physical properties of small-scale sand ripples on the
sea bed is important for determining the bed roughness felt by currents and waves, for …

Laboratory studies of ripples and dunes show robust relations between bedform geometry
and both fluid flow conditions and grain size. These empirical relations are derived at …

The development of bedforms under unidirectional, oscillatory and combined‐flows results
from temporal changes in sediment transport, flow and morphological response. In such …

A comprehensive database of existing (since 1954) field and laboratory measurements of
ripple geometry is compiled and combined with newly collected field data to examine the …

We integrate published data sets of field and laboratory experiments of wave ripples and
use genetic programming, a machine learning paradigm, in an attempt to develop a …

Recent laboratory and field experiments have shown the inability of existing oscillatory flow
ripple predictors to accurately predict both ripple size and ripple planform geometry …

Although normal isotropic hummocky cross‐stratification is commonly interpreted to be the
deposit of large‐scale ripples, there are many reasons why this may not usually be the case …
