基于MIKE21的汾河水库突发环境事件数值模拟OA北大核心CSCDCSTPCD
Numerical Simulation of Pollutant Migration in Fenhe Reservoir Following an Accident Using the MIKE21 Model
为揭示汾河水库突发环境事件时污染物的迁移扩散规律,识别水库潜在风险源,采用实测数据对二维水动力-水质模型进行率定与验证,并以二甲苯泄漏为例,考虑事件源、浓度、排放入口、风动力因素,设置11种情景模拟污染物的迁移扩散规律.结果表明,污染物初始质量浓度决定汾河水库受污染程度;风动力是影响污染物扩散的关键因素,风向决定污染物扩散路径,风速增加1倍时,污染物扩散速率和超标面积分别增加46.5%和64.2%,风速相同时,西北风比西南风更有利于污染物的扩散;…查看全部>>
We predicted the potential migration and attenuation of pollutants in Fenhe reservoir following an acci-dent using two-dimensional hydrodynamic and chemical transport models. Taking the leakage of xylene as an ex-ample, we simulated its movement under 11 scenarios by considering accident source, contaminant concentration, location of the entry to the reservoir, as well as wind speed. The results showed that initial concentration con-trolled risk of the…查看全部>>
