Experimental study for Hydraulic Characteristics as the Permeable underlayer width of Rubble Mound Structure

사석방파제 투수층 두께에 따른 사면상의 수리특성에 관한 실험연구

In this study, the effects on hydraulic characteristics are discussed as the permeable underlayer width of the rubble mound structure changes. A series of hydraulic experiments were performed and wave run-up, reflection and set-up were investigated. Results indicated that wave run-down was affected by the water out from the permeable underlayer during down-rush. As the width increased, relative wave run-up decreased.
