- W2040312079 abstract "분포형 수문모형은 컴퓨터 하드웨어의 급속한 발전과 GIS를 이용한 수문지리공간정보에의 접근성 및 활용성 증가에 따라 근래에 많은 발전을 이루게 되었다. 하지만 물리기반의 분포형 수문모형은 입력자료 구축 및 모형구동에 많은 시간과 노력이 필요하며 수문자료가 불충분한 미계측 유역에서는 모형의 구축이 어렵다는 한계점을 지니고 있다. 이에 본 논문에서는 개념적 격자 물수지 기법을 이용한 개념적 분포형 수문모형 S-RAT을 개발하였다. S-RAT 모형은 집중형 수문모형의 자료구축의 간편성과 분포형 수문모형의 공간적 유출해석 능력을 동시에 만족할 수 있으며 격자기반 레이더강우자료를 활용할 수 있다. 또한 전처리과정 및 유역의 지형자료 추출 기능을 탑재함으로 상용 GIS 분석 도구들에 대한 의존성이 없는 장점을가진다. 본 논문에서는 도시유역인 중랑천 유역과 산지유역인 내린천 유역 적용을 통해 S-RAT 모형의 유출모의능력 및 매개변수의 시공간적 전이성을 확인하였으며 지상강우와 레이더강우의 입력 자료로써의 활용성을 확인하였다. The distributed hydrologic model has been considerably improved due to rapid development of computer hardware technology as well as the increased accessibility and the applicability of hydro-geologic information using GIS. It has been acknowledged that physically-based distributed hydrologic model require significant amounts of data for their calibration, so its application at ungauged catchments is very limited. In this regard, this study was intended to develop a distributed hydrologic model (S-RAT) that is mainly based on conceptually grid-based water balance model. The proposed model shows advantages as a new distributed rainfall-runoff model in terms of their simplicity and model performance. Another advantage of the proposed model is to effectively assess spatio-temporal variation for the entire runoff process. In addition, S-RAT does not rely on any commercial GIS pre-processing tools because a built-in GIS pre-processing module was developed and included in the model. Through the application to the two pilot basins, it was found that S-RAT model has temporal and spatial transferability of parameters and also S-RAT model can be effectively used as a radar data-driven rainfall-runoff model." @default.
