| 摘 要： | 以汉江中下游为例,基于MIKE 11模型的降雨径流模块、水动力模块、对流扩散模块建立了汉江中下游的降雨-径流模型、水动力模型和对流-扩散模型,通过对模型进行率定和验证,表明该模型具有较理想的模拟效果;在此基础上运用构建的模型模拟了汉江中下游2003年冬季、夏季不同水文情况下,突发性水污染事故中污染物的运移扩散过程,定量模拟了突发性水污染事故发生后,汉江不同地点处污染物到达的时间和浓度值,并对突发风险事故的影响范围、程度、时间做出定量预报.

| Abstract: | Based on the sub-models of MIKE 11 model Rainfall-Runoff model(RR model),Hydrodynamic model(HD model),Advection-Diffusion model(AD model),the corresponding three models used for the middle and lower reaches of Hanjiang river are established.Through the coefficients calibration and the model verification,the models receive a better simulation.The diffusing and moving processes of pollutants from the burst water-pollution accidents are timely simulated by using the above established models under the different hydrological status in winter and summer of 2003.These models can quantitatively predict the reaching time and concentrations of pollutants at any places in the middle and lower of Hanjiang river when water-pollution accidents burst out. |
