N2 - This paper describes impulsive wave force due to breaking solitary waves impinging and overtopping an impermeable breakwater upon a sloping beach. A two-dimensional volume of fluid (VOF) type numerical model named COBRAS (COrnell BReaking And Structure), based on the Reynolds-Averaged Navier-Stokes (RANS) equations and the k - ε turbulence closure model, is firstly calibrated against present laboratory experiments with fairly good agreements and then employed to study the impulsive wave force correlated with structure failure mechanisms due to waves interacting against the breakwater. Both the effects of wave nonlinearity and freeboard are addressed. Influence of entrapped air-bubble accompanied breaking waves on reducing wave force is also discussed.
