Numerical Simulation of Two-dimensional Wave Propagation by Reef Island

波浪在岛礁地形上传播的重要特征之一是波浪的破碎,为了研究近岸岛礁地形下波浪传播特性,本文采用基于Boussinesq方程的FUNWAVE1.0模型,对于二维岛礁地形上波浪的传播过程进行了数值计算,通过数值计算结果与物模实验结果的对比分析,研究了数值计算模型中波浪破碎模拟参数的取值,研究结果可为实际工程波浪破碎过程的模拟分析提供参考。

Wave breaking is an important characteristic of wave propagation by reef island. To explore the wave propagation by inshore reef island, FUNWAVE1.0 model based on Boussinesq equation has been used to calculate the process of wave propagation by 2D reef island. The calculation results are compared with the physical model experimental results in order to analyze the wave breaking parameters simulated by using the numerical model. The analysis results will provide a reference for the simulation of wave breaking process in engineering practice.
