Problem of Non-Contact Surface<br />
Velocity <strong>Measurement</strong><br />
1. Conversion factor is subject to change<br />
We decided conversion factor from observed<br />
data at Uono-<strong>River</strong> and Tone-<strong>River</strong>,<br />
We must get more data and verify the factor<br />

The <strong>Discharge</strong> by Non-contact<br />
Surface Current Meter us<strong>in</strong>g the<br />
conversion factor made from<br />
Uono-<strong>River</strong> and Tone-<strong>River</strong> data<br />
are settled <strong>in</strong> less than about 5%<br />
of float observation discharge.
