Abstract

<p>In the present study, to build a river-discharge measurement system without floats in upstream, we have attempted to apply a radio current meter in a flood-flow measurement in Tone River. The observed results indicate that the water-surface velocity using a radio current meter has an influence of the wind. However, the measurement accuracy of the velocity using a radio current meter considered by the effect of wind are good agreements with those of ADCP. It is noteworthy that the coefficient of float show increasing and decreasing trend as water depth and the averaged coefficient of float are as same as the standard value. Therefore we can apply the standard value of the coefficient of float to the velocity using a radio current meter.</p>
