Increased risk of disasters due to rain
In East Japan and Tohoku, it is expected that it will rain over a wide range on the 19th, and there are places where the emergency construction of the embankment broken by Typhoon No. 19 has not been completed, so the risk of disasters is increasing in the Kanto Regional Development Bureau etc. Is calling for vigilance.
The Kanto Regional Development Bureau and Tokyo Regional Meteorological Observatory held a press conference in Saitama City on the afternoon of the 18th.
According to it, for the four rivers of the Koshibe River, Kuji River, Miyako Iku River, and Naka River whose dyke broke down in Typhoon No. 19, the standard of announcement such as “flooding dangerous water level” indicating the risk of flooding is reduced to the usual 70% In addition to lowering operation, it means that the amount of water in the upstream dam is reduced and preparations are being made.
In four rivers, emergency repair work is being carried out at nine locations, of which six will be completed within 18 days, but three will not be completed.
Of these, construction is scheduled to be completed on the 19th at the site of Higashimatsuyama in Saitama Prefecture on the Ikugawa River and on the 20th at the site in Kawagoe City, Saitama Prefecture on the Koshibe River.
In addition, the construction site of Hitachi Omiya City in Ibaraki Prefecture on the Nakagawa River is scheduled to be completed on the 21st of this month.
The Kanto Regional Development Bureau calls for caution as the risk of disasters such as levee breakage has increased because repair work on the dyke has not been completed and the water level has been high due to typhoons.
