Abstract

Steep, steady non-linear waves have been generated onto strongly sheared currents. Quantitative, full-field velocity measurements have been made for a number of wave/current combinations using the method of Particle Image Velocimetry (PIV). For one of the combinations, the measured kinematics are compared to the estimate obtained by adding the stretched current profile to the predictions from irrotational theory. The steadiness of the conditions is assessed by calculating the vorticity distribution for different cycles in the wavetrain. Finally, the measured wavelengths for a range of wave frequencies are used to estimate the effective current.
