河川・湖沼における採水ドローンの開発と実用性の検証

抄録

We developed a new method of water sampling by using UAV with a bleached attachment for a 1-L water bottle. To confirm the practical performance, water sampling for water quality and environmental DNA surveys was conducted in Haizuka dam reservoir and Saba river.

The result indicates that the UAV method can be applied to water quality and eDNA surveys in many kinds of water bodies, such as lakes/ponds and rivers. In the dam reservoir, this method enables efficient water sampling for a short period of time, compared with that using boat. In the river, it can apply for the water sampling in the stream with a high velocity (1.46m/s).
