The study combines historical records of dam construction on the Mekong River, water level observations, and agricultural productivity statistics, with satellite data as proxies for salinity index and vegetation coverage. The findings show that increased reservoir capacity significantly reduces downstream freshwater discharge, decreases rice yield, and intensifies saltwater intrusion, while annual electricity output partially mitigates these effects. These impacts are most severe during dry seasons and closer to the shore. Two mechanisms are identified: the disruptive but temporary ”filling effect” in the first-year post-dam completion, and the persistent, smaller ”operational effect” over time. 2025-04 submitted doi:10.5194/egusphere-egu25-20779 3862 public paper EGU General Assembly 2025 Vienna 27 April-02 May 2025 conference FALSE no info:eu-repo/semantics/conferenceObject
