内容記述タイプ Abstract
内容記述 In this study, the authors developed an automatic discharge measurement using ADCP and DIEX method. We observed the four different hydraulic phenomena downstream of Teshio river. 1) flow at the time of normal and flood stage, 2) flow at the salinity intrusion, 3) flow at the covered with ice, 4) flow at the salinity intrusion while being covered with ice. In the case of the normal and flood flow, the discharge was calculated by DIEX method using horizontal flow velocity distribution of H-ADCP. When the salinity intrusion or being covered with ice, firstly, we estimated the fresh-salt water interface and bottom height of ice using the velocity profile and bottom tracking of V-ADCP. Secondly, we calculated the unit width discharge to measured velocity profile. Thirdly, we calculated the logarithmic law flow velocity profile of the open channel flow with same the unit width discharge. Finally, the discharge was calculated with DIEX method using one representative point of the logarithmic law flow velocity profile. The discharge accuracy was about ±10% under the four different of hydraulic phenomena. This result showed that it was possible to calculate the discharge automatically without man working.
