本文采用Berkhoff为验证缓坡方程的不同计算方法可信度所使用的地形,对基于Boussinesq方程的FUNWAVE和基于NS方程的SWASH两种时域模型进行了比较分析,通过与实测数据对比,结果显示两种模型都能达到较好的精度,整体上FUNWAVE略好于SWASH,但基于相同的模型设置,SWASH运行速度远远快于FUNWAVE。综合考虑两种模型的精度与运行速度,SWASH模型被认为更具实用性。

In this paper,the bathymetry was applied in the comparison between two time domain wave models FUNWAVE and SWASH. The governing equations of each model were introduced. Both FUNWAVE and SWASH show a good agreement with the experimental measurement,while FUWAVE is a little better than SWASH in general. But SWASH is much faster than FUNWVE,which is believed to be more competitive in the practical use.
