Reflected wave coefficients of sloping beaches are obtained in experiments in regular waves. Three straight beaches consist of 1/10, 1/3 and 1/2 sloping angles. A simple linearized model which replaces breaking wave zone with hypothetical semi-infinite fluid domain of constant depth is proposed for calculation of reflected waves. The constant depth of hypothetical domain is varied proportional to the incident wave heightThe linearized model is solved numerically by the boundary intergral equations, and the results are compared with measurements. For 1/10 slope, calculated reflected wave coefficients agree well with measurements both in the amplitude and the phase. As an application of this model, wave-exciting force/moment of a floating structure near beach are compared in two cases, with or without sloping beach. Those results are presented graphically.
