Different Effect of Cloud Seeding on Three Dam Basins, Korea

This study shows that cloud seeding should be planned by considering the dam reservoir characteristics as well basin characteristics. First, collection efficiency of increased rainfall is compared for three basins (Boryeong Dam, Yongdam and Namgang Dam basins) located in western part Korean Peninsula. Second, additional runoff volumes those from are with each other. Finally, change water supply capacity evaluated operation supply. In this study, simulated using WRF−ARW model, and, additionally, four different data generated scenarios a increase 5, 10, 15, 20% used more practical evaluation. The results show situation Boryeong better than other two basins. More active necessary However, it has also been found alone cannot solve problems above findings indicate carefully planned. It can vary dam-by-dam. Cloud might effective every season one dam, but only Spring another basin, while dams, summer or fall best option. target an important issue. Just mild could to secure much dams. Even though dams considered practically same climatic zone, conditions required differ completely.
