Abstract

The generation of long waves due to the refraction of wave groups over a shelf is reexamined. The appropriate boundary conditions for calculating the second-order mean free-surface displacement are discussed. Numerical results for a plane shelf are presented, which are different from those given by Mei & Benmoussa (1984).
