Summary

The interrelationships between turbulent flow, sediment transport and bedform theory are critically reviewed. Progress in these fundamental fields of physical sedimentology is hampered by lack of evidence and theory on: (1) the precise nature of the link between inner and outer zone flow structures at high Reynolds numbers, (2) the effect of grain roughness and bedforms upon inner and outer zone structures, (3) the effects of transported grains upon turbulence generation and dissipation, (4) the possible anisotropy of turbulence and its role in sediment suspension. A number of proposals are made concerning these problems and some suggestions for future research are presented.
