摘　　要：选择在波浪破碎模拟中表现较好的破碎指标GOMOD15和SAMOD17进行比较.首先将两者分别引入SWAN模型,然后利用实验室水槽试验(包括斜坡和平底条件)和现场观测数据比较两者对SWAN模型波浪模拟的影响.总体来看,随着坡度的逐渐变缓,SAMOD17与GOMOD15的结果差异逐渐显著,对于文中的所有算例,采用GOMOD15的模拟结果均更接近实测值.鉴于GOMOD15的更好表现且在模型计算时不需要人为调整其参数,因此在采用SWAN模型模拟波浪破碎时推荐使用.GOMOD15 and SAMOD17,well-performed breaker indexes in wave breaking simulation,were selected for comparison.Firstly,the two breaker indexes were introduced to the SWAN model,and then their effects on the wave simulation of the SWAN model were evaluated by comparing the computational results with the laboratory(including both sloping and flat bottom cases)and field observed data.On the whole,the difference between SAMOD17 and GOMOD15 is gradually significant with the decrease of the bottom slope.The simulation results using GOMOD15 are closer to the measured values of all the cases in this research.As GOMOD15 gives better performance and does not need to adjust its parameters artificially in simulation,it is recommended as the breaker index when the SWAN model is used to simulate wave breaking.
