摘要
珊瑚礁水动力学是一个涉及生态、环境、地质和工程学的交叉课题,其水动力学研究不仅为珊瑚礁海域生态系统的维护和海岸线的演变提供一定的理论参考,还能为海岸的防灾减灾以及岛礁工程的建设提供一定的决策依据。回顾了国内外珊瑚礁海岸水动力问题的研究与进展,从现场观测、理论模型、物理模型试验和数值模型4个方面对当前该领域的研究进展进行了综述,并提出今后现场观测研究对象可关注南中国海的珊瑚岛礁,理论分析方法可侧重考虑非线性波浪理论,物理模型试验可采用大型波浪水槽和港池来复演现场尺度的水动力问题,数值模型可采用计算流体力学(Computational Fluid Dynamics,CFD)方法对波浪与珊瑚礁相互作用进行精细化模拟,本文旨在为今后国内珊瑚礁水动力学方面的相关研究提供一定的借鉴和参考。
Coral reef hydrodynamics is an interdisciplinary subject involving the knowledge of ecology,environment,geology and engineering. This subject not only offers theoretical reference for the ecosystem protection and the coastline evolution around the reef island,but also serves the decision-making process for the reef-coast hazard prevention and the reef-island engineering construction. In this study,based on a comprehensive literature review as well as the author’s previous work,the state-of-the-art research advances on coral reef hydrodynamics are summarized in view of the following four aspects: field observation,theoretical analysis,laboratory experiment,and numerical simulation.The research prospects are subsequently provided as follows: the field observation could focus on those reefs in South China Sea,the theoretical analysis could attempt to use the nonlinear wave theory,the laboratory experiment could reproduce the hydrodynamics at field scale based on the large-scale wave flume as well as the wave basin,and the numerical simulation could turn to the Computational Fluid Dynamics (CFD) to simulate the interaction between wave and reef at finer scale. This study serves to guide the future relevant researches on coral reef hydrodynamics in China.
