This study conducted runoff analysis for the floods in Sep. 1954 and Oct. 2004 by the distributed runoff model for Yanase Dam basin in the upper Douzangawa River, where once become devastated by an operation of Besshi copper mine and recovered by afforestation and tree species conversion. Subsequently, a relationship between the tree species conversion over 50 years and changes of flood runoff characteristics, and a reduction effect of forest in peak discharge of flood were examined.As a conclusion, authors presumed approximately 20 percent improvement of the peak discharge reduction by tree species conversion. It was supposed that the difference of flood runoff characteristic were explained by parameters in relation to rainfall interception and evaporation function of forest, and in Yanase Dam basin, the change of tree density sensitively influenced on runoff characteristics.
