• RAINFALL-RUNOFF ANALYSIS FOCUSED ON RAINFALL PATTERN AND ASSESSEMENT OF DAM EFFECTS ON FLOOD CONTROL IN TONE UPPER RIVER BASIN

抄録

To clarify the effects of difference from rainfall pattern on runoff phenomenon contributes to the further development of the flood control measures commencing with dam control. Elucidating those effects is very useful to examine flood control plan. In this study, authors made pseudo rainfall patterns based on Typhoon Kathleen in September 1947 in Tone upper river basin and examined the effects of difference from rainfall pattern we created on runoff phenomenon. Moreover, authors verified the flood-control ability of Yanba dam in Agatsuma basin. In consequence, it was indicated that peak discharge at Yattajima point of observation was up 15 percentage point from peak discharge in Typhoon Kathleen depending on rainfall pattern. Furthermore, it was indicated that Yanba dam is 4 percent effective in decreasing water level at Yattajima point.
