Abstract Recently, sense of value of the citizen has diversified according to convenience of life improving rapidly. On the river works, preservation of environment is required in addition to flood control and water resource. However, environment has the various elements such as water quality, ecosystem, landscape etc.. Therefore, image of environment differs in the individual. Presently, the index which evaluates river environment is BOD. But, river environment cannot be evaluated only with this index. Then, we examined comprehensive appraisal technique. In this research, 4 rivers located in the southern part of Miyazaki prefecture were dealt with. From both sides in physical and chemical environment and ecological environment, river environment was measured quantitatively. Influence to the river environment with the human activity in the rivers was appraised quantitatively. With appraisal, the radar charts drew the observed results were used. The appraisal result matched the impression when investigating. From this, we concluded that comprehensive appraisal technique was developed.
