- W2006163906 abstract "본 연구는 전지구 위성 강우자료와 글로벌 지형자료를 이용하여 유출분석을 수행하여 계측자료가 부족한 지역에 대한 강우-유출 관계를 파악할 수 있는 방법을 제시하는 것을 목적으로 하였다. 사용된 위성 강우자료는 CMORPH와 GSMaP_NRT자료를 사용하였고, 글로벌 지형자료는 GTOPO30 및 GLCC자료를 이용하였다. 유출분석을 위한 도구는 IFAS를 이용하였다. 강우 정확도 평가에서 관측강우자료와의 상관계수는 CMORPH 및 GSMaP_NRT에서 0.37 및 0.30로 분석되었다. IFAS를 이용한 유출분석에서 매개변수를 보정하지 않은 경우에도 위성 강우자료를 이용한 모의 첨두유출량이 관측유출량과의 상대오차가 낮았다. 따라서 계측자료가 없는 유역에서의 적용성이 있는 것으로 사료된다. 향후 대표적인 비접근 지역인 북한지역에 대하여 위성강우 및 글로벌 지형자료를 이용하여 유출분석에 활용할 계획이다. The objective of this study is to suggest a method for estimating rainfall-runoff relationship using runoff analysis with satellite rainfall and global geographic data for the region due to lack of observed data. This study uses CMORPH and GSMaP_NRT as satellite rainfall data, and GTOPO30 and GLCC as global geographic data. IFAS is used for runoff modeling. In the evaluation of rainfall data, the correlation coefficients of CMORPH and GSMaP_NRT with observed data are 0.37 and 0.30 respectively. Calculated peak runoffs using IFAS show small relative errors with observed data in case of parameters are not calibrated with satellite rainfall data. Therefore, the methods suggested in this study could be applied to ungauged watershed. In the future, this study will analyze runoff for North Korea, a representative inaccessible region, using satellite rainfall and global geographic data." @default.
