摘要
本研究基于ECOMSED模式,引入变边界技术,建立厦门湾三维动边界潮流模型,以模拟具有大面积滩涂的厦门湾水动力过程。模型综合考虑九龙江上游径流和M2,S2,N2,K1,P1,O1等6个主要分潮的作用,对整个厦门湾及其毗邻海域进行了一个多月的模拟,最后将模拟结果与实际观测资料进行对比验证,结果表明本研究所建立的模型可以较好地反映厦门湾海域的潮流运动过程,为进一步研究河口海湾地区提供了可靠的技术基础。
According to the bathymetry of Xiamen Bay, a three - dimensional variable border numerical tidal model for Xiamen Bay is established in this paper. The model is based on ECOMSED model （ Blumborg et al, 2002）. In order to simulate the flooding - drying process over inter - tidal Mudflat, an approach to represent high and low tides is developed for this three - dimensional model. Tidal processes are controlled by harmonic processes including lunar and solar semidiurnal and diurnal cycles. The model simulates current dynamic processes from Apr. 1,2003 to May 10, 2003 and is validated by comparing observed data with the model - generated tidal elevations and currents. The results indicate that the wetting and drying process is properly represented in the ECOMSED model.
