Abstract

This research focuses on dam reservoir operation effective in flood mitigation and water resource reservation on a seasonal scale. Based on the relationship between discharge characteristics in the upper watershed of Chao Phraya River and flood occurrences in the lower watershed, it was clarified that the dam reservoir operation most effective in the rainy season was determining the lowest reservoir volume in August for the Sirikit Dam reservoir and in July for the Bhumibol Dam reservoir, and storing water until November. Furthermore, by the probability evaluation on the free reservoir capacities of both dams estimated from the predetermined lowest reservoir volume and inflow volume in both dams, the dam reservoir operation considering the importance of flood mitigation and water resource reservation on a seasonal scale can be achieved.
