Abstract
Actual conditions of bank damage in some rivers of Tohoku district of the past decade were investigated. It was found that the nondimensional tractive force of flow and the ratio of high water channel width to radius of channel curvature, the ratio of low water channel width to distance of talweg from the channel bank are major factors determining the occurence of river bank damage. In order to make models to predict the location and type, scale of river bank damage multi-variable analysis (Quantification II) was carried out using some of these variables and a composed variables as factor variables. Among the obtained models, the model to predict location of river bank damage was highly evaluated by field data.
