Control Mechanism and Resistant Strength of Common Reeds against River Bank Erosion

Abstract

Control effect of common reed against bank erosion were studied at the Tama River. Erosion-resisting strength of river bank having a common reed were estimated by focusing on soil properties and reed roots. It was found that a common reed functioned so as to restrain the advancement of erosion. Erosion-resistance mechanism of a common reed was clarified by a laboratory curved channel which had a submerged vegetation model attached to the outer bank. Also, the resistance strength of common reeds was estimated by newly developed apparatus.
