Miyagi Yoshida River broke down Local towns, etc. `` Low levee '' and raised again October 14 23:07
The Yoshida River embankment in Ogo-cho, Miyagi Prefecture, which was destroyed by Typhoon No. 19, was lower than the surrounding embankments after the Great East Japan Earthquake, so the town and local residents repeatedly asked the country to raise the bank. I understand that. The country says that “rainfall exceeding expectations is the main cause of the breakdown”.
The typhoon No. 19 caused the Yoshida River embankment in Yodogawa, Ono-cho, Miyagi Prefecture, to break down, flooding more than 100 houses.
According to the Ministry of Land, Infrastructure, Transport and Tourism and the town, the broken levee was found to be lower than the surrounding levee in a joint inspection conducted by the country and the town in June 2011, three months after the Great East Japan Earthquake. .
The cause of the low is unknown, but the town and fire brigade have since requested the Ministry of Land, Infrastructure, Transport and Tourism to raise the dike.
However, no uplifting work was carried out, and measures were taken to arrange the sandbags about 1 meter high last month, but in this breach, the sandbags were washed away and the levee collapsed greatly.
Mr. Yasunori Suzuki, head of the Ogo-cho fire brigade, pointed out, “I was worried because it was lower than the surrounding embankment. Because the breakup has just begun from that part, it must have happened to happen.”
On the other hand, Deputy Director Yuri Yagi of the Kitakami River Downstream Office of the Ministry of Land, Infrastructure, Transport and Tourism said, “It was true that it was lower than the surrounding area, but we thought it could withstand the expected rainfall. The main reason for the breakup is that the relationship with the dike being lower than the surroundings is unclear. "
