Urban flood risk assessments play a crucial role in urban resilience and disaster management. This paper proposes comprehensive method for assessment prediction that is based on environmental attributes the operational characteristics of pipe networks. Using central area Zhengzhou as case study, an integrated evaluation index system was developed, entropy weight applied to quantify indicators. A loosely coupled RF-XGBoost model constructed predict different rainfall scenarios. The results indicate (1) overall study exhibits increasing trend from northeast southwest, with medium- high-risk zones being predominant; (2) spatial distribution pattern closely aligns but shows slight variations under influence network risks; (3) demonstrates superior predictive accuracy multi-factor coupling When characteristics, attributes, risks are comprehensively considered, Nash–Sutcliffe Efficiency (NSE) predictions improves 0.85 (when using only characteristics) 0.94. provides valuable insights technical support mitigating risks.
