| 摘 要： | 本文提出了珠江广州段COD数值模拟的控制方程、计算格式、方法、步骤和程序,并结合野外实测资料进行了参数校正和验证计算。并根据计算和实测结果对珠江广州段COD污染的时空变化特点进行讨论。本文的主要特点是:(1)考虑了COD模型的各项影响,尤其是感潮河网涨退潮交替的不定常流影响;(2)提出了感潮河网不定常流条件下COD模型数值计算中的叉口处理,即关联任意个河段的叉口处受涨退潮影响的处理方法。

| Abstract: | A model for tidal current and COD dispersion in Pearl River, Guangzhou Reach was developed. The model was calibrated and verified based on observed tidal flow and measured COD data. The variation of COD value was discussed according to both measured and calculated results. |
