Future Hydrological Drought Analysis Considering Agricultural Water Withdrawal Under SSP Scenarios

Hydrological drought is assessed through river flow, which depends on runoff and water withdrawal. This study proposed a framework to project future hydrological droughts considering agricultural withdrawal (AWW) for shared socioeconomic pathway (SSP) scenarios. The relationship between AWW potential evapotranspiration (PET) was determined using deep belief network (DBN) model then applied estimate projections of the twelve global climate models (GCMs). 12 GCMs were bias-corrected quantile mapping method, variables generated, flow estimated soil assessment tool (SWAT) model. standardized index (SRI) used changes in characteristics. results revealed higher occurrence severe future. Droughts would be more frequent near (2021–2060) than far (2061–2100) when considered. also SSP5-8.5 SSP2-4.5. that increased PET due rising temperatures primary cause frequency severity. will accelerate severities Yeongsan River basin.
