摘要:
利用多普勒雷达产品、精细化数值预报产品和城市密集自动雨量观测站数据，以内涝积水模型和内涝风险等级划分原理为核心，研发精细化到街区的南宁市暴雨内涝监测系统，实现城市内涝的实时监测、提前预警和风险预估，并将内涝预警信息以多种途径发布；将该系统用于2015年5月4日的短时强降雨造成城市内涝过程，验证结果表明：模拟结果与观测结果基本相符，最大积水深度和位置基本一致，但个别点存在两者异常偏大情况，排水管网初始场数据不完善是导致模拟结果产生异常的主要原因。应用结果表明，该系统具备一定的暴雨内涝动态监测预报能力，对提高对城市暴雨内涝灾害的监测预警和风险评估水平起到了一定作用。
Abstract:
Using Doppler radar products, refined numerical prediction products and urban intensive automatic rainfall observation station data, taking waterlogging model and waterlogging risk grading principle as the core, we developed a rainstorm waterlogging monitoring system in Nanning City refined to the block to realize real-time monitoring, early warning and risk pre-warning of urban waterlogging, estimate and publish waterlogging early warning information in multiple ways. The system is applied to the process of urban waterlogging caused by short-term heavy rainfall on May 4, 2015. Verification results show that the simulation results are basically consistent with the observation results, the maximum depth and location of water accumulation are basically the same, but there are two abnormal large cases at individual points. Imperfect initial field data of drainage network is the main reason for abnormal simulation results. The application results show that the system has a certain ability of dynamic monitoring and forecasting of rainstorm waterlogging, and plays a certain role in improving the level of monitoring, early warning and risk assessment of urban rainstorm waterlogging disasters.
