Abstract: Surging water demand necessitates strategic water management to maintain efficiency and accessibility. In Thailand’s Eastern Economic Corridor Project, water demand escalated from 2005 to 2018 by 54%, prompting water management plans using pipe diversion. However, this plan merely shifts scarcity issues due to limitations and climate uncertainties. The Water Stress Index assessed the impact using distributed hydrological modelling, revealing the 3Rs scenario, and a dry season rice cultivation lowered by 26%. Specific basins still face extreme stress. Integrating scenarios can refine and alleviate stress, suggesting a combined scenario approach, improving Water Stress Index and efficiently identifying vital water reduction strategies.
