摘要

乌克兰的利沃夫市有一个综合下水道系统，其中主要的下水道功能是由波尔特瓦河在地下混凝土通道中形成的。本研究针对利沃夫城市洪涝灾害，建立了改进的利沃夫污水系统水力模型，该模型考虑了压力流模式，并考虑了城市洪涝灾害的极限排放能力。对2022年7月5日的强降雨事件进行了水力建模。通过水力模拟，观察到实际洪水量与模拟的主要下水道溢流量之间存在很强的相关性。

Critical overflow of the main combined sewer in the city of Lviv: A case study of recent extreme flooding

The city of Lviv in Ukraine has a combined sewer system where the main sewer function is performed by the Poltva River, shaped in the underground concrete channel. In this study improved hydraulic model of Lviv sewerage system was developed, taking into account a pressure flow mode, as well as limit discharge capacities, corresponding to the urban flooding. Hydraulic modelling was conducted for the heavy rainfall event on July 5, 2022. A strong correlation was observed between the actual flood volume and the modelled overflow of the main sewer, obtained through hydraulic modelling.
