- Abstract:
- Urban waterlogging control requires coordinated blue-green-gray infrastructure, yet quantitative studies on their synergistic effects remain insufficient. This study proposes a reconstruction framework for Shijunyan drainage area in Mianyang based on the sponge city concept, and conducts a quantitative analysis of the contribution rates of different waterlogging prevention systems using the SWMM. When the study area met the waterlogging control standard, the contribution rates of source reduction systems, pipe drainage systems, and storage-drainage systems were 5%, 91%, and 4% respectively. Results demonstrate that upgrading drainage pipe networks constitutes the primary task for waterlogging control in high-density urban areas of mountainous cities, but requires synergistic integration of source-control sponge facilities and storage-drainage systems to mitigate diminishing marginal effects.
