| 摘 要： | 在平面二维三角形网格有限体积法求解水流模型的基础上,建立了高精度水质输移数学模型,并用具有解析解的对流输移经典算例对模型进行了验证,结果表明该模型具有守恒性好,精度高等优点。最后将该模型应用于钱塘江河口上游突发性水污染事故的动态模拟,对突发事故的影响范围、程度、时间作出了定量预报,评估了突发事故对饮用水源地取水口水质的影响,为钱塘江河口上游水域突发性水环境污染事故的应急预案提供指导。

| Abstract: | A high-order transport model is established based on the triangle unstructured shallow flow model and finite volume method.The model is examined by a sample with exact solution for physical concentration.A comparison between computed results and exact solution demonstrates very good agreement.Finally,the model is applied to simulate the diffusing and moving processes of pollutants from the burst water-pollution accident under different hydrological conditions.The model can quantitatively predict the reachin... |
