流量観測高度化に向けた複数の流量観測手法の観測精度の比較検証

抄録

River discharge observation that usually float method is selected needs advancement of precision, safety and efficiency. Now, there are several techniques proposed and used but each method has some advantages and some disadvantages. For example, ADCP has higher precision than other methods but that needs higher costs and more times.

In this report, river discharge observation data by several techniques that are float method, ADCP, radio current meter, image analysis method are compared in terms of precision, safety, and cost at Ryogun and Kushida Bridge in Kushida River.
