Abstract
The Hokkaido Regional Development Bureau organized the Committee for Conservation of the River Environment in the Kushiro Wetland in 1999. The Committee summarized and released an epoch-making proposal for conservation of the river environment of the Kushiro Wetland in 2001. Governments and other organizations have since conducted measures based on the proposal for restoring and conserving the Kushiro Wetland. In 2011, river restoration in the Kayanuma area, one of the most symbolically important measures, was completed and various monitoring research is being executed. This report discusses specific effects of the project. The Kushiro Wetland has the function of a natural flood control basin and reduces the risk of damage by flooding. Work to restore and conserve the KushiroWetland thus greatly contributes to maintaining the function of flood control. This report also discusses specific contributions to flood control by the Kushiro Wetland.
