Abstract

Random waves with a significant height H^ produce a maximum run-up of CH^ on the face of a coastal structure, where coefficient C is determined by the wave and wall characteristics. Unless this run-up is greater than R^, the freeboard of the structure, then there is no overtopping (apart from wind-blown spray). That is 1 - R, / CH, >0 for overtopping to occur. The parameter 1 - R, / CH, is used in an analysis of overtopping data and a new regression model is evaluated which, unlike existing expressions, satisfies the relevant physical boundary conditions. The new model is inherently suitable for representing the small overtopping discharges associated with normal design conditions. 1 Introduction An important criterio
