| 摘 要： | 本文用考虑底摩擦的折射模式计算了浅水中波高和波向分布。作为一个例子,根据不同的摩擦系数和不同的边界条件计算了一种简单海底地形的折射系数、衰减系数和折射角,所得结果与不考虑底摩擦的折射模式结果进行比较,发展它们之间存在一些差异,表明在浅水中底摩擦对波高有一定影响。

| Abstract: | In this paper , the distributions of wave height and wave direction in shallow water are obtained from a wave refraction model with bottom friction. As an example,the refraction factors, attenuatin coefficients and refraction angles are computed over a kind of simple bottom topography with various friction coefficients and different boundary conditions. The results are then compared with those from the model without bottom friction, and some differences between them are found, showing certain influence of bottom friction on wave height. |
