- Abstract:
- Urban waterlogging has become an important factor restricting urban development, and the urgent problems to be solved include fully understanding the causes of urban waterlogging and formulating corresponding disaster prevention strategies. A one-dimensional and two-dimensional coupled waterlogging model was constructed based on PCSWMM software. According to the results of multi-scenario simulation, the characteristics and different causes of waterlogging disasters in the main urban area of Haikou City were analyzed, and a combined disaster control scheme were proposed. The waterlogging model based on PCSWMM was capable of providing reliable information to support cause analysis and disaster prevention decision-making. The causes of waterlogging in the main urban area of Haikou City mainly included excessive rainfall, tidal backwater, insufficient drainage capacity of river channels and pipelines, low lying and flat terrain. The regional waterlogging was effectively alleviated through the pipelines and river channels reconstruction in combination with the addition of reservoirs and drainage pumping stations.
