Abstract
In the present study, to build a river-discharge measurement system without floats in upstream, we have attempted to apply a radio current meter and image-processing technique to a flood-flow measurement in Tone River. We conducted eight observations during a typhoon in 6 and 14 October, 2014. We used an ADCP, a radio current meter, a high-definition camera and an aerovane. The observed results indicate that the water-surface velocity measurement using a radio current meter and image-processing technique ware influenced by the wind. However, the measurement accuracy of the velocity using the radio current meter and image-processing technique with the effect of wind into consideration was in good agreement with that of ADCP.
