Research on the Causes and Treatment Methods of Urban Flood Points

Urban flooding, caused by extreme rainfall in the context of global warming, poses significant challenges to people, society, and the economy. One particular flood-prone area in Guiyang’s Huaxi District serves as our research focus. Field visits revealed that inadequate infrastructure, suboptimal management systems, limited local resources, and a lack of safety awareness among residents contribute to the flooding issue. To address this, we propose implementing Low Impact Development (LID) techniques to transform the area into a sponge-like site. Using the Storm Water Management Model (SWMM), we constructed a flood simulation model to compare pre- and post-transformation scenarios. Results show that the proposed approach effectively mitigates flooding. Moreover, we emphasize improving flood prevention and control management systems by standardizing practices and enhancing drainage and flood prevention facilities. These measures aim to bolster the overall urban flood control system and ensure the city operates safely. Our study provides valuable insights for building a resilient Guiyang, acting as a reference for sponge city construction and strengthening flood control efforts.
