Summary: The project has produced the following: - The first set of reliable experimental data for waves interacting with a narrow jet-like current in three dimensions. This includes regular and irregular waves, together with bed stresses in some cases; this bed stresses were only measured for those wave conditions that yielded significant bed stresses. Surface profiles and velocities, mean and wavelike were measured. - One extensive data set in two dimensions. This is concerned with regular and irregular waves and with both following and adverse currents. Bed stresses are measured in some cases, as appropriate, and bed was taken to be smooth, roughened and slatted. Surface elevations and velocities were measured. - A second set of two-dimensional data, with the emphasis on strongly sheared currents. The shear is strongest at the surface and was generated artificially to simulate wind-driven currents. Velocities and elevations were measured for both regular and irregular waves. - Two data sets concerned with three-dimensional motions in wave flumes. Velocity data was obtained across sections of the flumes. - Field data from four sets of tests off the French coast of the English Channel. Two of the four sets are particularly useful and some of the motion is nearly two-dimensional in character. - A number of mathematical models to describe wave-current interactions in two and three dimensions and for regular and irregular waves. These are specific to the prescribed configuration. - Numerical methods to described complete flow motions in two dimensions for regular waves. These simulate the viscous sub-layer and turbulent boundary layer in the vicinity of the bed, the main essentially inviscid domain and the shear layers near the free surface in one model. This represents the leading edge of mathematical modelling and numerical analysis.
