Abstract
본 연구에서는 농업용 저수지의 저수율, 선행토양함수조건(AMC) 및 Huff 시간분포가 첨두유출량에 미치는 영향을 몬테칼로 시뮬레이션을 통해 분석하였다. 저수지 저수율, 선행토양함수조건 및 Huff 시간분포의 적용에 따라 4가지 경우에 대해 첨두홍수량을 산정하고 비교한 결과, 50~300년 빈도의 첨두홍수량은 저수율 100% 또는 AMC­III로 일괄 적용했을 때 각 조건의 발생확률을 고려한 첨두홍수량에 비해 20~30% 크게 산정되었다. Huff 3분위를 일괄 적용했을 때의 첨두홍수량은 발생확률을 고려한 Huff 분위 적용에 비해 5% 크게 산정되어, AMC와 저수지 저수율에 비해 첨두홍수량에 미치는 영향이 적었다.
This study analyzed the effect of irrigation reservoirs, antecedent soil moisture conditions (AMC) and Huff time distribution on peak discharge using Monte Carlo simulation. The peak discharge was estimated for four different cases in combination of irrigation reservoir capacity, AMC, and Huff time distribution. Applying 100% reservoir capacity or AMC­III, the peak discharges corresponding return periods of 50~300 years were overestimated by 25~30% compared to those of cases that considered the probability of occurrence for individual condition. Applying the 3rd quantile huff distribution, the peak discharges were overestimated by 5% over the peak discharge that considered the probability of occurrence. The overall results indicated that the effect on the peak flood of Huff distribution was less than AMC and reservoir storage.
