Abstract: Based on InfoWorks ICM model, the 1-D and 2-D coupling hydrodynamic model of the experimental area in Longhua District, Shenzhen was established. According to the actual rainfall measured in Longhua District on May 3rd, 2018 and June 8th, 2018, the model parameters were calibrated and validated by comparing water level modeling results with water level monitoring data of several manholes in experimental area. According to the modelling results of experimental area under 2 h rainfall in 50 years frequency, the main reasons of waterlogging was summarized as insufficient drainage capacity of main pipe, too much impervious surface and water level jacking of downstream sewage intercepting pipe. A comprehensive renovation scheme for preventing waterlogging was proposed. The scheme included spongy city reformation, drainage pipe optimization and downstream manhole intercepting reconstruction. By constructing the model of waterlogging comprehensive renovation in experimental area, the results show that the regional waterlogging prevention is effectively improved and waterlogging risk is eliminated.
