- W2016296001 abstract "실제유역을 선정하여 지속가능 개발량을 평가하였다. 시험유역은 경북 상주시 양촌리 일대(3.89<TEX>$textrm{km}^2$</TEX>)이며, 관측수위와 모형 추정수위를 분석함으로써 visual MODFLOW모형을 검정하였다. 2003년 3월 19일부터 2004년 3월 18일까지 모형 추정수위와 관측수위를 분석한 결과, 잔차의 평균은 0.0009m, 잔차 제곱합은 7.245<TEX>$m^2$</TEX>, 절대평균오차는 0.094m 제곱근오차는 0.141m였으며, 모형의 효율은 92%로 나타났다. 강우자료를 분석하여 평년, 10년, 30년 빈도 한발년을 선정하고, 이들에 대한 지속가능 개발량을 평가하였다. 시험유역 침투량에 대한 지속가능 개발량의 비는 평년 빈도 한발년(1992)은 14.5%, 10년 빈도 한발년(1994)은 15.1%, 30년 빈도 한발년(1982)은 15.2%로 각각 나타났다. 본 연구결과는 지역특성을 고려한 지하수 개발 및 관리계획 수립을 위한 기초자료로서 활용될 수 있을 것이다. An experimental watershed was selected and sustainable yield was evaluated. The study area(3.89<TEX>$textrm{km}^2$</TEX>) was located in Kyungpook Sangju Yangchon-dong. The visual MODFLOW was verified by comparing the observed and estimated groundwater table. The analysis of the observed and estimated groundwater table from 19 March 2003 to 18 March 2004 showed that the average error was 0.0009m, the error sum of squares 7.245<TEX>$m^2$</TEX>, absolute mean error 0.094 m, root mean square error 0.141m, and the model efficiency was 92%. The normal, 10- and 30- year drought frequency years were selected and sustainable yield was evaluated in these periods. Ratios of sustainable yield to the annual infiltration were 14.5% for the normal year(1992), 15.1% for the 10-year(1994), and 15.2% for the 30-year drought frequency year(1982). The results of this study can be used as a basic information for groundwater development and management planning considering regional characteristics." @default.
