A CASE STUDY ABOUT MAINTENANCE MANAGEMENT ON RIVER RESTORATION PROJECT

Abstract

Many river restoration projects are conducted in Japan. These projects may need maintenance about overexuberant vegetation. It is an important problem to establish the appropriate maintenance system for river restoration project. Good maintenance management system by the local people is established in Azamenose which is a floodplain restored by MLIT. In this study, we detailed the maintenance management system, and tried explaining the reason why the system had been well-functioning by conducting oral questionnaire survey against local people and government officer (administrator). As a result, resident participation in planning stage, environmental events for children, external praise against effort conducted in Azamenose, were considered to be important for inhabitants’ independent-minded participation to maintenance management.
