Abstract
Agricultural small dam reservoirs in Korea are vulnerable to flooding because of insufficient flood control capacity and deterioration such that reservoir water level is likely to rise rapidly and a large amount of water release quickly to downstream without flood warning. In this study, we performed hydrologic analysis to estimate design flood(200 years return period ${\times}1.2$) and also evaluated the effect of siphon spillway as a structural countermeasure for flood control and mitigation by applying reservoir routing to the Jipyeong reservoir, located in Sangju, Korea. The results show that the design flood was calculated at $284.3m^3/s$, and water level and water release decreased by 40cm and $91m^3/s$, respectively.
