Abstract

The methodology is applied to typical regions in Guangdong Province to simulate responses to historical extreme drought events (1963-1964 and 2021-2022), while future extreme drought scenarios projected by General Circulation Models (GCMs) are constructed to evaluate system performance.

Simulation results demonstrate that this approach effectively reduces the vulnerability of water supply systems. ✓ Through systematic infrastructure optimization, the water shortage intensity during consecutive water-deficient months in drought periods can be controlled below 10%, with simultaneous reduction in total regional water deficit.

This methodology demonstrates significant potential in mitigating industrial production losses caused by water scarcity during future extreme drought events under climate change, thereby providing crucial water supply support for regional sustainable development .
