Abstract

The bottom shear stress vector under the action of combined waves and currents are directly measured using the UCL shear plate device. The three corresponding velocity components have also been recorded simultaneously, enabling the results to be expressed in terms of a friction factor. The scope of the work extends that of earlier tests on regular waves, and includes three sequences of random waves propagating above a fixed rough bed in still water and over two orthogonal currents. The results agree well with earlier observations from tests on regular waves, and f can be predicted from standard formulae.
