A new parameter representing the maximum depth-integrated wave momentum flux occurring over a wave length is proposed for characterizing the wave contribution to nearshore coastal processes on beaches and at coastal structures. This parameter has units of force per unit crest width, and it characterizes flow kinematics in nonbreaking waves at a given depth better than other wave parameters that...

Wave absorbers installed in front of revetments are effective reducing wave overtopping and inundation caused by periodic waves. The absorbers’ mechanism long-period waves such as tsunamis storm surges is not clearly understood. This study conducted a physical modeling test numerical analysis based on large eddy simulation model using in-house code to examine the characteristics according revet...

This study attempts to refine a model named the Integrated Formula of Wave Overtopping and Runup Modeling (IFORM) improve prediction performance mean wave overtopping discharge for broader range installation conditions. The empirical formula describing relation between maximum runup has been re-examined. A set piecewise formulas is implemented in IFORM by optimal reconstruction coefficients dep...

Understanding the spatial distribution of wave overtopping water behind coastal protection structures is essential for assessing safety level regions defences. The volume determines planning and arrangements critical infrastructures (e.g., railways, roads buildings) in regions. This study presents a series laboratory-scale physical modelling experiments to investigate plain vertical seawall wit...
