Abstract Human-induced warming is intensifying the water cycle, increasing risk of extreme precipitation and rainstorm-induced floods (RIF), posing a challenge for sustainable socioeconomic development Yellow River Basin (YRB). Future flood risks under dual impact climate change urbanization are less than adequately understood. In this study, we selected 9 indicators to formulate an RIF evaluation Model based on hazard disaster-inducing factors, sensitivity disaster-prone environment, vulnerability disaster-bearing areas (HSVM). We combined analytical hierarchy process (AHP) entropy weight (EW) method estimate during historical (1950–2014), near-term (2021–2040), mid-term (2041–2060), long-term (2081–2100) periods over YRB SSP245, SSP585 scenarios. found decreasing along southeast northwest direction, moderate high in middle lower YRB. Using period as baseline, increased by 8.34%-18.29% (11.66%-28.93%) SSP245 (SSP585) High was identified YRB, particularly urbanized regions. Compared period, 30.46%-79.39% (29.14%-93.18%) Specifically, were precipitously provinces such Shandong, Henan, Shaanxi, 47.00%-91.50% (50.67%-169.51%) scenarios The increase Henan Shandong reached 58.02%-283.05%, larger period. This study highlighted YPR, calling urgent mitigation measures disaster reduction.
