Abstract

This research aimed at analyzing comparison results between in gravel and sand bed with respect to the detailed Acoustic Doppler Current Profiler (ADCP) measurement in a velocity, depth, and flow rate data based on Acoustic Doppler Velocimeter (ADV) measurement result. Conclusionally, similar results were shown for gravel and sand bed in velocity, depth and flow rate data using ADV and ADCP measurement. The results of the flow rate show a relative error mean of 3.5 - 4.8% in the gravel bed and 0.02 - 3.2% in the sand bed, which is better performance than the mean error of 5% suggested by United States Geological Survey (USGS). The results can be used as a basis data for the measurement of ADCP and potentially able to be utilized for the more detailed uncertainty analysis of ADCP flow rate measurement.

본 연구는 하상재료에 따른 ADCP의 측정 적합성을 평가하기 위해 하상 재료가 다른 자갈 하상과 모래 하상인 지점에서 ADCP의 유속, 수심 및 유량 자료를 ADV의 측정 결과와 비교 분석하였다. 연구결과 자갈 하상과 모래 하상에서의 ADV와 ADCP를 이용한 유속 분포와 수심 측정 자료는 비슷하게 나타났다. 유량측정 결과 자갈 하상에서 평균 3.5 - 4.8%, 모래 하상에서 평균 0.02 - 3.2%의 상대오차 범위를 나타내어 USGS에서 제시한 평균 오차 5%의 범위보다 작아 신뢰가 높은 결과인 것을 알 수 있었다. 이러한 결과는 향후 ADCP의 하천 적용성에 대한 기초자료로 활용될 수 있으며 ADCP의 불확도 평가에 중요한 자료로 이용될 것으로 판단된다.
