Study on Relation between Horizontal-Vertical Distribution of Vegetation and Channel Hydraulic Characteristics in Rivers

Abstract

It is needed to get fundamental information about vegetation in rivers for developing a future river plan from view points of environment. The authors attempt to understand the relation between horizontal-vertical distribution of vegetation and channel hydraulic characteristics in rivers by using the result of the detail field survey in the Fuji River. At first, area of horizontal distributions of 21 kinds of vegetaion are compared with 5 major hydraulic parameters in lkm length each along the river. In the next, relative height of each vegetation from the standardized water level is also compared with, size of vegetated area at each lkm, then some interesting results are represented.
