DOUBLE WALLED, LOW REFLECTION WAVE BARRIERS

R.J. Cox, P.R. Horton, S.H. Bettington

Abstract


The effectiveness of a second perforated barrier seaward of a solid wave barrier in significantly reducing wave reflections and simultaneously improving wave protection is demonstrated in the paper. The indicated optimum seaward wall porosities and overall widths can be readily incorporated into practical structural designs for small craft facilities in relatively sheltered waters with limited wave periods. Results of an extended laboratory testing program and specific application to a recently designed and constructed structure are presented.
