| 摘 要： | 基于波浪能量谱理论,导出了考虑底摩擦的复杂地形能量谱的联合折射绕射数学模型,在能量谱为单一频率组成波时,模型则简化为规则波的联合折射绕射方程.实际计算结果表明:本文提出的随机波浪联合折射绕射数学模型是合理的,在浅水区应该考虑底摩擦作用.

A Mathematical Model of Combined Refraction-Diffraction for Random Waves |
| |
| Abstract: | Based on wave spectrum theory, a spectrum's combined refraction - diffraction mathematical model (RDMM) with bottom frition is derived, which can be simplified to regular wave's combined RDMM when the energy spectrum represents a single frequency composition wave. The results of practical calculations show that the present RDMM for random waves is reasonable, and that bottom friction should be considered in shallow water. |
