Amplifying Flood Risk Across the Lower Yellow River Basin, China, Under Shared Socioeconomic Pathways

The ecological conservation and high-quality development of the Yellow River basin (YRB) has been adopted as a major national strategy China. However, YRB is still afflicted by floods. Here, we proposed flood risk indicator using direct economic loss degree improved SNRD (station-based nonlinear regression downscaling model) simulated extreme precipitation processes. correlation coefficient downscaled average CMORPH CMIP6 data reached 0.817. Moreover, evaluated hazard across based on sixth phase Coupled Model Intercomparison Project (CMIP6) under different SSPs. Under SSP126, SSP245, SSP585 scenarios, areas with increasing hazards during 2015–2045 accounted for 65.2, 69.0, 64.5% entire YRB. In spatial pattern, decreased from southeastern to northwestern parts When compared pattern risks in 2015, regions high expanded slightly low shrunk slightly. Higher can be observed middle lower particularly These findings are critical mitigation warming climate.
