Abstract: An oscillating water tunnel with a 12 metre long working section of cross-sectional dimensions 0.5 x 1 metre has been designed, built and tested. With this equipment wave boundary layers can be simulated for practically the full range of waves that may be produced in the sea or in wave flumes. The range of orbital amplitudes is 0.1 to 4 metres. To date the system has been used to determine bed shear stress at fixed beds, while studies of ripple form on a number of sediments with different specific gravities are now in progress. The oscillating water tunnel may also be used as a tool for conducting research into the fundamental properties of oscillatory boundary layers, e.g. velocity profiles and turbulence characteristics. Yet another use may be for the study of oscillatory flow around submerged objects such as pipelines or piles.
