The Henan section of the Yellow River Basin (3.62 × 104 km2, 21.7% Province), a vital agro-industrial and politico-economic hub, faces frequent rainfall-induced geohazards. 2021 “7·20” Zhengzhou disaster, causing 398 fatalities CNY 120.06 billion loss, highlights its vulnerability to extreme weather. While machine learning (ML) aids geohazard assessment, geological hazard susceptibility assessment (RGHSA) remains understudied, with single ML models lacking interpretability precision for complex disaster data. This study presents hybrid framework (IVM-ML) that integrates Information Value Model (IVM) ML. uses historical data 11 factors (e.g., rainfall erosivity, relief amplitude) calculate information values construct prediction model these quantitative results. By combining IVM’s spatial analysis ML’s predictive power, it addresses limitations conventional models. ROC curve validation shows Random Forest (RF) in IVM-ML achieves highest accuracy (AUC = 0.9599), outperforming standalone IVM 0.7624). All exhibit AUC exceeding 0.75, demonstrating strong capability capturing rainfall–hazard relationships reliable performance. Findings support RGHSA practices mid-Yellow urban cluster, offering insights sustainable risk management, land-use planning, climate resilience. Bridging geoscience data-driven methods, this advances global sustainability goals reduction environmental security vulnerable riverine regions.
