Abstract: This paper describes an experimental investigation into return flow generated by rectangular resonators on semi-infinite harbor entrances. The study included: the bandwidth of the reduced energy spectrum transmitted into a harbor, the concomitant reflected wave spectra and the energy available for return flow. This paper is intended to provide data for the design of on-channel harbor resonators to: (1)Eliminate or reduce the transmission of a selected band or harmful wave frequencies; or (2)maximize orbital velocities near the bed so as to prevent the influx and deposition of littoral sediments in harbor entrances; or (3)maximize return flow power extracted from the wave action in the resonators, or all three.
