广佛珠江河网区石油类污染数值模拟研究

基于EFDC模型，构建了广佛珠江感潮河网区三维水动力模型；同时，通过耦合石油类污染物水力输运与悬沙吸附一沉降过程，构建石油类水质数学模型，从而更全面客观地模拟水体石油类污染物的迁移转化过程。通过2001年1月实例模拟及验证，表明模型能较好地模拟再现珠江水体石油类浓度变化过程，为日后珠江水环境质量监控与水质改善、城市河涌整治成果评价及预测等提供技术支持。

Numerical Simulation of Oil Pollution in Guangzhou-Foshan Pearl River Network

Based on EFDC model, a three dimensional hydrodynamic model was constructed for Guangzhou pearl river network. In addition, an oil quality model was also built by combining advection, diffusion of aquatic pollutants and adsorption and settling processes of oil in water by suspended sediments. The proposed model was calibrated and applied to field observation case of Jan. 2001, the results shows that the model can reproduce oil concentration variation in Pearl River, which also indicates that the proposed model can applied to water quality monitoring, evaluation and prediction for future water environmental remediation to pearl river and its inner creeks.
