A random wave model combining wave refraction and diffraction has been developed,which is based on the higher order approximation parabolic mild slope equation and uses the linear superposition theory.By comparison with the irregular experiment of Vincent and Briggs,the results of calculation agreed well with that of experiment.Some conclusions derived from the numerical calculations will be important for practical engineering calculations.
