Abstract

An eigenfunction expansion method is used to analyze the propagation of a plane wave train along a rectangular channel, the side walls which are provided with regularly spaced thin vertical strips. The presence of such strips may produce cross-channel seiching and energy dissipation. The method is extended to take into account the dissipation of energy at each pair of strips. Analytical solutions are obtained for the general case. Theoretical results of wave attenuation along the channel are compared to laboratory experiments, Battjes (1965).
