罗源湾潮流及海水半更换期的数值研究

Numerical Studies on Half-exchange Period and Tidal Current in Luoyuan Bay

本文建立了罗源湾二维潮波的数值模型,计算并分析了罗源湾潮流的时空分布特征,结果表明:数值计算所得到的潮流场与实测潮流场基本符合,基于这一潮波的数值模型,本文还建立了该湾物质迁移扩散的数值模型,计算出罗源湾海水的半更换期为10天。

A two-dimensional numerical model of tidal current in Luoyuan Bay has been established. The tidal current fields were calculated and the results were in good agreement with the measured ones. Based on the tidal current model, this paper also presented an advective-diffusion numerical model to calculate the half-exchange period of sea water in Luoyuan Bay. the result is 10 days.
