Abstract
A field experiment to measure transmission of wave energy through a porous rock island breakwater at Elmer on the South coast of the UK is described. Preliminary estimates of transmission, reflection and dissipation are discussed with reference to the statistical parameters of the incident wave field, and with respect to gravity band and low frequency response. For the wave conditions observed during the measurement period, results indicate that transmission is primarily affected by wave steepness and energy flux magnitude, but may also be changed by the existence of standing waves within the breakwater structure. Examination of the low frequency spectrum shows that seiches are excited in the bays between salients. The geometry of the bays appears to support such modes.
