Wave Transmission and Force on Fabric Tube Breakwaters

A numerical model based on finite-amplitude, shallow-water wave theory is developed to predict irregular wave breaking and transmission as well as wave force on an innovative Shore-RIB structure that consists of one or two tubes held by an anchored fabric shroud. The numerical model slightly underpredicts the measured transmission coefficient which decreased linearly with the increase of the ratio between the crest elevation of the structure and the incident spectral significant wave height. The maximum fabric tension predicted using the computed wave force is in fair agreement with the measured tension. The difficulties in predicting the temporal variations of the fabric tension due to intermittent tube oscillations are discussed using the measured and predicted results.
