Experimental Study on Regular Wave of Transmission Coefficient through a Hollow-Block Mound Breakwater

Besides wave attenuation, hollow-block mound breakwater acts as artificial reef which could protect the marine biology and repair the marine ecological environment. Transmission coefficient is the main index of breakwater’s wave attenuation effect evaluation. In this paper through the sectional model experiment on the special assembled hollow-block mound breakwater under regular wave, affecting factors (opening size, water depth, wave period, incident wave height) of the transmission coefficient of breakwater were studied. The main factors that influence the wave attenuation of the hollow-block mound breakwater are the opening size of the hollow-block and the depth of the water while the wave period and the wave height of the incident wave have less influence for the wave attenuation of the breakwater. The research results can provide the reference for the following theoretical research and engineering practice.
