Attempt of the mehr Nature method in a small river

Abstract

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.
