Acoustic Doppler Current Profilers (ADCPs) have been widely utilized for assessing streamflow discharge, yet few comprehensive studies were conducted to evaluate discharge uncertainty in consideration of individual uncertainty components. It could be mostly because it was not easy to determine which...

유량 측정 성과 자료의 목적은 무엇인가? | 유량 측정 성과는 유역의 설계 홍수량 산정 및 관측 지점의 수위-유량 관계곡선 구축 등 이치수를 위한 설계나 유역의 장· 단기 계획의 수립 시 기초자료로 사용되고 있으며, 설계나 연구 등의 목적을 위해 2 · 3차원 수치해석 모델의 입력 및검 ? 보정 자료로서 사용되고 있다(Jung et al., 2000; Son et al. | |
GUM 표준안의 한계점은 무엇인가? | 그러나, GUM 표준안도 모든 계측 분야에 적용할 수 있는 일반적인 안으로, ADCP 등과 같은 특정 장비에 기반하고 정형화된 유량산정 알고리즘에 구체적으로 적용하는 단계에 이르기 위해서는 추가적인 적용 작업이 필요하였다. 이에, Lee et al. | |
측정 불확도를 산정하거나 공시하는 이유가 드문 원인은 무엇인가? | 그러나, 각종 장비로 측정된 유량성과에 대한 신뢰성을 나타내는 지표인 측정 불확도를 산정하거나 공시하는 경우는 드물다. 그 이유로는 불확도 산정에 필수적인 이론적인 표준안이 통일되지 않았고 유량 측정에 영향에 미치는 다양한 불확도 인자들에 대한 정보가 부족하였기 때문 이다. 따라서 단순히 반복 측정된 유량의 표준편차를 불확도로 잘못 이해하거나, 프로펠러유속계 기반 도섭법의 경우 간편법인 ISO 748 (ISO, 2007) 등을 활용하고 있어, ADCP 등최근 도입된 측정방법에 대한 불확도 산정에 적용함에 있어 한계가 있었다. |
