This study suggests a novel approach of estimating stream flow discharge using the Synthetic Aperture Radar (SAR) images taken from 2015 to 2017 by European Space Agency Sentinel-1 satellite. Fifteen small to medium sized rivers in the Han River basin were selected as study area, and the SAR satelli...

물 부족 문제의 현황은 무엇인가? | 물 부족 문제는 전 세계인구의 3분의 1이 겪고 있을 정도로 심각하며 기후변화와 함께 인구 증가와 경제 성장, 도시화 등으로 인하여 더욱 심화되고 있다(Vörösmarty et al., 2001; Döll et al. | |
유량자료의 활용도는 무엇인가? | 유량자료는 수자원 계획 및 정책 결정, 관련 시설 운영 등의 수자원 관리에 가장 기초가 된다(Marsh, 2002). 가장 일반적인 유량 산정 방법은 현장 관측소에서 수위를 연속하여 관측 하고 수위-유량 관계식을 이용하여 유량을 추정하는 방법이다. | |
일반적인 유량 산정 방법을 이용한 추정방법이 어려워지고 있는 이유는 무엇인가? | 가장 일반적인 유량 산정 방법은 현장 관측소에서 수위를 연속하여 관측 하고 수위-유량 관계식을 이용하여 유량을 추정하는 방법이다. 하지만 현장 관측 및 자료 접근이 매년 경제적, 기술적, 제도적인 장애물로 인해 어려워지고 있어 이를 보완할 수 있는 방안이 필요하다(Vörösmarty et al., 2001; Bjerklie et al. |
