Wave-induced runup and wave transmission due to overtopping are two critical variables to be considered in design of coastal structures. Many studies have been performed on different armor units, but there is no generalized information available on CORE-LOCTM armor layer performance with respect to wave runup and transmission. Thus, an experimental study was performed to investigate the runup and transmission response of a CORE-LOCTM armor layer. Wave runup and transmitted wave heights were measured for a wide range of wave, water level, and structure conditions in order to develop predictive tools for CORE-LOCTM layer response. A new empirical model to predict runup levels was developed from an existing model for rock revetments. Furthermore, a semi-quantitative analysis of transmission data was conducted to give insight and guidance for design purposes.
