Abstract: To assess the overall status of waterlogging control in cities, we developed an evaluation index system consisting of 17 indices spanning four key aspects: construction of waterlogging prevention project, management of waterlogging prevention, intelligent waterlogging prevention, and ecological space management. By using cloud model, we evaluated the overall effectiveness of urban waterlogging control in Yandu District of Yancheng City, a low-lying area in Jiangsu Province. Results reveal a comprehensive score of 85.11 for urban waterlogging control in the study area, reflecting a good level of waterlogging control. The proposed method proves effective in assessing urban waterlogging control as it identifies areas in need of improvement, thus providing valuable insights for addressing any existing weaknesses.

Key words: urban waterlogging control, comprehensive evaluation, evaluation index system, cloud model, Yandu District of Yancheng City
