【Abstract】 In this paper, a numerical model is developed to describe the nearshore wave diffraction and refraction by using the irrotationality of the wave number vector and the wave energy conservative equation The Battjes relation is employed in the computing model to solve nearshore wave transformation of propagation wave The model is tested against laboratory measurements for the case of a submerged circular shoal on a slope, where both refraction and diffraction are equally significant The computing results show that the data of the computation and the test are well identical更多还原
