中文摘要： 当前，我国正处于工业化建设的转型阶段，受工业基础薄弱和生产工艺水平的限制，污染物的违法排放、事故排放以及其他意外排放等事件频发，不仅严重破坏水生态系统，更是威胁沿岸城市供水安全，影响正常的社会生产生活。突发性水污染事故发生后，科学地快速准确评估污染事故影响程度与范围，确立基于敏感目标的污染物应急控制阈值，采取高效合理的应急处置措施，对于及时正确处置水污染事故具有重要意义。.因此，本项目针对复杂条件下突发水污染事故应急模拟需求开展研究，采用数值模型与物理水槽实验相结合的方法，对传统水质模型在水污染事故应急模拟中的不足进行改进，构建复杂河道形态下突发水污染事故应急模型，对水污染事故的影响程度、时间和范围进行精确预警；并基于不同应急措施的物理过程，对应急效果进行准确模拟分析与评价，为我国突发水污染事故的精细高效应急工作提供科学依据与支持。

英文摘要： Although China has been in the transition phase of the modern industrialization, the low pollutant treatment rate and overload emissions is still the main causes of pollution at present because of the weak industry foundation and limitation of production technology level. It caused that the water pollution problem is becoming more and more serious. Especially when frequently non-normal pollutants discharge such as violation rule emission, industrial accident and other incidental leak has happened; it could release large amount of pollutants instantaneously, which brings severe damage to water environment. These water pollution incidents have been not only causing serious damage to aquatic ecosystems, but also threatening the water supply safety of riverside city. When a water pollution incident happened, it would be great significance that the efficient and reasonable pollution accident emergency disposal technology has been taken after the pollution accident influence scope and destructiveness had been scientific evaluated.. According to the need of sudden water pollution incident emergency simulation, this project will develop a fine water pollution incident contingency model under the complex conditions by improving the deficiency of traditional water quality model in water pollution incident simulation based on the method of combining the numerical model and physical flume experiment. The developed model will be applied to accurate predict the water pollution accident influence scope and destructiveness, and fine analyze and evaluate the effect of contingency measures based on the different physical process. The outcome could provide a scientific basis and support for the precise and efficient water incidental pollution contingency response in China.
