| 内容記述 | Omisaka Valley is located on the Mt.Iwate (altitude of 2038 m) hillside in the southern part of Shizukuishi-cho, Iwate-gun, Iwate Prefecture. A mudflow occurred in the main stream regionon August 18, 2006, and many buildings in the valley were ruined. A car, which was sitting in a parking lot, was carried in the mudflow, and one person was injured. Furthermore, the prefectural road was closed by debris flow deposition for an extended period of time. The prefectural road is important as a sightseeing road, leading to hot springs and skiing and mountain climbing destinations. Debris flow was deposited upstream in the main stream region, which produced anxiety about the possibility of second debris-flow event. For this reason, examining traffic congestion at the time of a heavy rain and thaw has regarded as an important subject. The rainfall on which I focus, i.e., the rainfall capable of moving earth and sand to generate a mudflow, is the rain at the source head located on the upper part of the Iwate-san. The rain characteristics of such a high-altitude mountain location have not been clarified. In this examination, I compare rain gauge observational data and the precipitation volume analyzed by radar- AMeDAS data. Moreover, to examine the risk of a future mudflow, I conducted an analysis with a Snake curve using a rain example. |
