摘要
本文采用波数矢量无旋和波能守恒方程建立了一个近岸水域波浪变形数学模型，模型中采用Ｂａｔｊｅｓ关系与波数矢量无旋，波能量守恒方程一起来求解近岸水域波浪折射绕射的联合影响的波浪要素。利用本文提出的数学模型对一个斜坡浅滩水域波浪折射绕射现象进行了验证，结果表明本文提出的近岸水域波浪变形的数学模型是可靠的，计算所得结果与试验结果是吻合的。
In this paper,a model has been developed to describe the nearshore wave transformation using the irrotationality of the wave number vector and the wave energy conservative equation.The Battjes relation is used in the mathematical model to solve wave refraction and diffraction on wave propagation.The model is tested with laboratory measurements for the case of submerged circular islands on a slope,where both refraction and diffraction are equally significant.The computing gives good results.
