초록

본 연구의 목적은 분포형 강우-유출 모형에 의한 유출량을 해석하는 것이다. 본 모형은 두개의 부모형으로 구성되어 있다. 하나는 수계망(drainage network) 을 통하여 운동파 모형(kinematic wave model)을 이용하여 분포적으로 추적되는 직접 유출 부모형이며, 다른 하나는 기저유출 부모형으로서 집중형으로 취급되어 유역 출구에서만 계산하도록 하였다. 본 연구에서 개발된 모형에 의하여 청미천 유역에 대한 유출량의 시간적, 공간적인 분포를 고려할 수 있었다.

The main goal of this study is a rainfall-runoff analysis using atopographically-based distributed model. It consists of two parts: one is a direct runoff submodel and the other is a baseflow submodel. The direct runoff submodel is a distributed model which routed through the drainage networks with a kinematic wave model. The baseflow submodel is considered as a lumped system. This model makes it possible to take the effect of areal and temporal distribution of storm into accout.
