RANDOM WAVE-CURRENT INTERACTION - THEORY AND EXPERIMENT

The purpose of this paper is to investigate the effect of uniform current on random waves. Theories are available to describe this interaction problem in the colinear cases. References are included that describe some of these theories and limited correlations with experimental data. These theoretical formulas are revisited in view of additional experimental data. The experimental data includes the interaction effect in a variety of water depths from relatively deep to shallow water. The water particle velocities and drag forces on fixed structures were also measured simultaneously in a few cases. Comparisons of the wave spectrum as well as the measured response spectra in both following and opposing current are made. Some interesting results are found in correlating the velocity and force spectrum due to conflicting interaction between wave-current effect and resulting forces. The interaction formulation may need modification based on this recent laboratory data.
