Abstract
MIDDLETON et al. (1987, Journal of Geophysical Research, 92, 9487-9493 ) have observed edge waves in the coastal ocean near Sydney, and postu lated that they are generated by the envelope of the radiation stress of wind-driven surface waves. In this paper we construct a simple theo retical model of this process. Analytical and numerical solutions show that radiation stress can generate free and forced edge waves, with t he greatest response occurring when there is a near-resonance between the forcing and the free edge-wave modes.
