| 摘 要： | 采用有限控制体积法和隐式离散基本水质方程,根据潮汐河网的特点,利用半控制体积概念和迭加原理,导出一种适合于任意形状的均匀混合型潮汐河网水质方程的分缓解法。应用广州潮汐河网两期水文水质同步实测资料,建立溶解氧动态模型,并进行了不同条件下的水质预测,初步揭示了广州潮汐河网半月潮期间的水质变化特性。

| Abstract: | This report presents a study of mathematical model for simulating and predicting water quality in Guangzhou tidal river network which is a part of Pearl River Delta Region . The tide belongs to a nonregular semi-daily tide. A solution method of water quality equation for a complex tidal river network is processed. A large mount of data is employed for calibration and verification of the DO-dynamic model. The simulation and prediction of water quality in Guangzhou tidal -river network are performed under various conditions. A characteristic variation of water quality during a semimonthly tidal period is discovered. |
