摘要
根据珠江口地质地貌特征,分析河口范围内海洋与陆地相互作用的特点,结合前人对河口湾水体交换原理及其应用的相关研究,提出适合于珠江口水体交换研究的计算方法,并利用MIKE3模型建立珠江口河口八大口门到外海伶仃洋的三维水动力模型,在一个月的模拟与验证下,利用模拟结果,计算出珠江口水体交换的时间,分析河流流量、外海潮汐与珠江口水体交换的相关性,并与同类河口水体交换的情况进行对比研究,分析影响珠江口水体交换时间的因素。
This paper proposed the calculation method of water exchange in Pearl River Estuary based on the characteristic of land and ocean interaction. The correlation among flow, tide and water exchange was analyzed. Furthermore, the study discussed the influencing factors of water exchange in Pearl River Estuary with the establishment of 3 - dimentional numerical model on MIKE3, and compared others water exchange periods based on the one month calculation.
