ON THE WEAK REFLECTION OF PERIODIC WATER WAVES OVER BOTTOM OBSTACLES.

Abstract

The weak reflection of water waves by bottom changes is studied for the case of slowly varying depth. Quadrature formulas for quantities of practical interest are derived by a WKB-iteration method via a Green's function. For long obstacles with a flat center section, it is found that under certain conditions only the sloping ends are responsible for the scattering. A slender body theory is also developed and explicit formulas derived. Agreement between two approaches is found to be good for low obstacles. (Author)
