摘要
In order to realize fast calculation of the low-frequency wave parameters inside a harbor under the resonant conditions, this paper studies the methods for calculating the low-frequency long wave parameters inside a slender harbor with the offshore irregular wave parameters through physical model experiments of harbor resonance. The results showed that the significant low-frequency wave height inside the harbor could be quickly and accurately calculated by both empirical formula and artificial neural network model based on the offshore irregular wave parameters and local water depth. By comparing the mean period of the low-frequency long waves inside the harbor and characteristic periods of the irregular offshore waves, no significant correlation was found between them. The artificial neural network model can still perform well in computing the mean period of the low-frequency waves inside the harbor based on the offshore irregular wave parameters and local water depth.
