Abstract
In an earlier work, Ismail and Wiegel (1983) observed experimentally that due to the effects of opposing waves, the spreading rates of a momentum jet are increased. They argued that the increases are caused by the radiation stresses generated by waves. Through numerical computations, the effects of opposing waves on momentum jets are reexamined in this paper. It is found that the radiation shear stress components S^ indeed increase the jet width. However, the radiation normal stress S-a actually decreases the jet width. The combined effects of both radiation stress components reduce the jet width. The true mechanism for increasing the jet width is due to the increase of bottom friction and turbulent intensity as the results of the wave and current interactions.
