This study proposes a method to generate runoff ensemble members using a rainfall-runoff model based on the shot noise process (hereafter the rainfall-runoff model). The proposed method was applied to generate runoff ensemble members for three drainage basins of Daerim 2, Guro 1 and the Jungdong, wh...

Shot noise란 무엇인가? | Shot noise는 다이오드나 트랜지스터와 같은 전자장치에서 발생하는 잡음(noise)의 한 형태이다. 이 noise는 발생시점에서 최댓값을 가지고 발생 시점 이후부터는 지수적으로(exponentially) 감소하는 특징을 가진다. | |
강우-유출 해석과정의 불확실성을 해결하기 위한 방편은? | 결과적으로 유출해석 결과는 상당한 오차를 보일수밖에 없는 구조적인 문제를 안게 된다. 이런 문제를 해결하기 위한 방편으로도입된 것인 확률적홍수예측이다. 발생 가능한 여러 시나리오를 생성하고(즉, 유출 앙상블) 이를 이용하여 확률적으로 발생가능한 미래 유출량을 예측하는 것이다. | |
도시유역의 침수피해가 가중되어 나타나는 이유는? | ,2018a). 특히, 도시유역의 경우에는 불투수면의 비율이 높기 때문에 짧은 도달시간, 첨두 유량의 증가 등의 현상이 나타나고, 이로 인한 침수피해가 가중되어 나타난다(Konrad, 2003;MLTMA, 2009; Jo, 2014; Song et al., 2015; Hofmann and Schüttrumpf, 2019). 침수로 인한 피해를 저감하기 위해서는근본적으로 예측 강우의 정확성이 개선되어 효과적인 예경보가 가능할 수 있어야 한다(MLTMA, 2009; Kim et al. |
