本研究试图改进名为波浪越浪和爬升建模综合公式（IFORM）的模型，以提高更广泛的安装条件下平均波浪越浪流量的预测性能。描述越顶流量和最大爬升之间关系的经验公式已被重新检验。 IFORM 中通过根据干舷赤字大小对系数进行优化重建来实现一组分段公式。改进后的IFORM改善了在干舷相对较高的范围内低估流量的倾向，同时保留了原始IFORM在波峰干舷相对较低的范围内的高性能。通过与安装在相对浅水深或陆地上的倾斜/垂直海堤的各种现有实验数据集进行比较，验证了改进模型的漫溢预测能力。还通过与众所周知的超越公式进行比较来检验预测准确性。定性和定量比较验证了当前模型能够在广泛的越顶条件下重现实验观察结果，并且本研究中提出的模型的性能与现有的代表性模型一样好。
This study attempts to refine a model named the Integrated Formula of Wave Overtopping and Runup Modeling (IFORM) to improve the prediction performance of mean wave overtopping discharge for a broader range of installation conditions. The empirical formula describing the relation between overtopping discharge and maximum runup has been re-examined. A set of piecewise formulas is implemented in the IFORM by optimal reconstruction of coefficients depending on the magnitude of deficit in freeboard. The refined IFORM improves the tendency to underestimate the discharge in the range of relatively high freeboard conditions, while it retains the high performance of the original IFORM in the range where the crest freeboard is relatively low. The refined model's capability for overtopping prediction is validated by comparison with various existing experimental datasets for inclined/vertical seawalls installed at relatively shallow water depth or on land. The prediction accuracy is also examined by comparison with well-known overtopping formulas. Qualitative and quantitative comparisons validate that the current model is able to reproduce the experimental observations over a broad range of overtopping conditions and that the performance of the model proposed in the present study is as good as existing representative models.
