Weakening flood, intensifying hydrological drought severity and decreasing drought probability in Northeast China

Northeast China is one of the largest agricultural regions in world and a strategically important granary for China. Information on hydrological extremes crucially water management. Yet, comprehensive studies extremes, both extreme flood drought events, based gauge large coverage observations are still lacking This study investigated observed with 124 gauges region ranging from 1950s to present first time. We find that mean discharge standardized decreasing over 80% gauges, no show significantly increasing extremes. The findings suggest sustainable management strategies should be employed meet demand long-term development. In addition, we peak volume correlated all motivating risk considering multiple variables together. Further, quantify probability changes severe droughts, events most suggesting number reducing.
