| 摘 要： | 结合廊坊城区地形地貌、市政工程、排水设施现状等，应用二维非恒定流基本方程和一维明渠非恒定流方程算法，构建城市积涝模型，结合区域自动站雨量实时监测数据、数值预报和预报员主观精细化降水预报，建立廊坊城市积涝动态预报预警系统，可实时估算、预报城市积水深度、积水时间等，预报并进行了业务试运行。系统以2012年7月21日廊坊市特大暴雨引起的城市积涝过程为例对系统进行了验证，结果表明：预报积水深度与实际积水情况比较接近，预报结果对城市防洪减灾有指导意义。

| Abstract: | Combining the current situation of landform, municipal engineering, drainage facilities in Langfang City, the two - dimen- sional unsteady flow equation and one - dimensional open channel unsteady flow equation algorithm were applied to eonstruct the urban waterlogging calculation model. Combined with the real - time monitoring data from regional automatic station, precipitation forecast and the forecaster~ subjective fine precipitation forecast, the establishment of the waterlogging dynamic forecasting and warning system in Langfang can carry on real - time estimation, prediction of city water depth and waterlogging time. Taking the waterlogging caused by the heavy rainstorm on July 21 in 2012 in Langfang as an example, the system was verified, and the result indicated that the forecasted waterlogging depth was close to the actual situation, which showed the forecast results had certain guiding significance for urban flood control and mitigation. |
