- W2223674561 abstract "본 연구는 개념적 준분포형 모형인 SLURP 모형의 소양강댐유역의 적용가능성에 대해 다루었다. SLURP모형은 강우의 시공간적 변화를 반영하여 강우-유출을 해석하여 관개계획 및 수자원 관리 효과를 판단할 수 있는 준분포형 모형이다. DEM으로부터 지형분석프로그램인 TOPAZ/SLURPAZ와 연계하여 빠르고 쉽게 지형매개변수와 지형자료를 획득할 수 있다. NOAA/AVHRR 위성영상을 이용하여 월별 NDVI를 산출하였으며, 대상유역 주변의 5개의 기상 관측소를 통해 일별 수문기상자료(이슬점, 일사량, 최대ㆍ최소 대기 기온, 상대습도 등)을 얻었다. DEM NDVI, 수문기상자료를 이용하여 1998년부터 2001년까지 4 개년도의 일별유출량을 모의하였다. 매개변수 최적화를 위하여 민감도 분석 및 SCE-UA 방법을 사용하였으며 대상기간의 Nash-Sutcliffe의 모형효율과 WMO 통계량을 통해 소양강댐 유역의 SLURP모형의 적용성을 검증하였다. The objective of this study is to test the applicability of SLURP (Semi-distributed Land Use-based Runoff Process) on Soyanggang-dam watershed. SLURP model is a conceptual semi-distributed form model that can be used to examine irrigation plan and the effects of proposed changes in water management within a basin or to see what effects external factors such as climate change or changing land cover might have on various water users. Topographical parameters were derived from DEM using TOPAZ and SLURPAZ. Monthly NDVIs were calculated from multi-temporal NOAA/AVHRR images during four years (1998 ∼ 2001). Weather elements (dew-point temperature, solar radiation, maximum/minimum temperature and relative humidify) were obtained from five meteorological stations within and near the study area. To simulate daily hydrograph during 1998 ∼ 2001, the model parameters of each land cover class were optimized by sensitivity analysis and SCE-UA method. Test result of SLURP was summarized by various statistics method (WMO volume error, Nash-Sutcliffe efficiency, mean error and coefficient of variation)." @default.
