멘-켄달 검정법은 어떤 경우에 사용하는가? | 보통 자연수계에서 측정되는 수질자료는 강수 등의 변수 때문에 특정분포를 따르지 않으며 결측치도 종종 발생하므로 통계적 기법을 이용하여 분석하고 해석하는 것이 필요하다 (Hirsch and Slack, 1984; Drapela and Drapelova, 2011). 멘-켄달 검정법 (Mann-Kendall test)은 월별 자료 수가 ≦40일 때 종종 사용된다 (Gilbert 1987; Reckhow et al., 1993). | |
도암호의 주오염원은? | 1 km 2 이며 객토 등의 영향으로 증가 추세에 있다 (Park, 2006;Wonju Regional Environmental office, 2012). 따라서 주오염원은 농경지에서 발생하는 비점오염물질 (탁수, 영양 염류 등)이며, 축산폐수 및 생활하수가 그 다음을 차지하고 있다. BOD, TN 및 TP의 오염원별 배출부하량은 토지 계가 각각 75. | |
센 기울기 검정법의 특징은? | , 1993). 센 기울기 검정법 (Sen’s slope test)은 수질자료에 대한 경향의 크기를 반영하며 신뢰한계에 따른 유의수준의 경향성을 결정한다. |
