用简单的一维浅水方程,与盐度变化和潮波同相位的长期观测结果验证,对海南岛清澜河口进行分析计算,可以得出它的一些特征。清澜河口虽然处在南海弱潮区,仍是典型的潮汐控制的强混合型;潮波被河口反射形成驻波,因而潮波、流速和盐度存在特殊的关系;盐度值和纵向扩散系数也可以进行估算,得出近乎实测值的结果。
Long-term observations validated by simple one-dimensional shallow water equations in phase with salinity changes and tidal waves are used to analyze and calculate the Qingkou estuary of Hainan Island, and some of its characteristics can be obtained. Although Qinghai estuary is located in the weak tidal zone of the South China Sea, it is still a typical strong mixed type of tide control. The tidal waves are reflected by estuaries to form a standing wave. Therefore, there is a special relationship between tidal wave, velocity and salinity. The salinity value and vertical dispersion Coefficients can also be estimated, yielding near-real-world results.
