This paper described the result of the examination on the evaluation system for the riparian environment. Fifteen items were used for the synthesized evaluation. These items were composed by not only the physical elements and the biotic elements but also the chemical elements and the sensuous elements. Qualification theory type 3 and cluster analysis were used to classify the features of the surveyed points. The followings were confirmed in this examination. The features of the riparian environment of surveyed points were evaluated by the proposed system. The chemical elements and the sensuous elements were important for the synthesized evaluation. The effect of the improvement of the riparian environment was objectively evaluated.
