抄録

In recent years, it is recognized anew that the plant of the waterside is effective in the function of shore protection. And many researchers push forward investigation of bank of a river protection by vegetation. But in small river, since management is easy, concrete shore protection remains mostly. And a small river is in the state where it is waterway-ized. If a stalk plant is given to the waterway-ized river, scouring and a deposition action will start it. Consequently, a current and deep water are gradually formed in stream bed and small water-route is made. When we give this method at a suitable interval, it is enabled to be rich in a scene and to also provide an aquatic-life living thing with rich nature. I made vegetation on the riverbank fish market, and this study conducted an investigation into a change of a flow, and we examined as one of the nature-friendly river improvement of construction.
