Riprap design for wind-wave attack - A laboratory study in random waves (EX 707)

This report is the official Hydraulics Research Station (HRS) account of an investigation into riprap stability in random waves carried out in co-operation with the Construction Industry Research and Information Association. This laboratory study arose out of earlier work on riprap done by HRS for the Civil Engineering Research Association. Rather than extend the original study it was decided to take advantage of improved laboratory techniques and examine the stability of riprap in paddle generated irregular waves which could be directly related to irregular waves occurring in nature, thus avoiding the problem of relating natural waves to the regular waves largely used in the former study.
