Kyushu's nationally managed river Embankment risk of flood breakage and flooding May increase significantly September 6 17:53
With this typhoon No. 10, it is expected that rainfall will exceed the maintenance level of rivers in rivers managed by six countries in total, Kagoshima prefecture, Miyazaki prefecture, and Kumamoto prefecture, and there is a risk of levee collapse and flooding. It can be very high.
The Ministry of Land, Infrastructure, Transport and Tourism calls for strict caution, as the risk of flooding is high in other rivers in Kyushu.
According to the Ministry of Land, Infrastructure, Transport and Tourism, the amount of rainfall on the 6th that exceeds the standard amount of rainfall for developing dikes in the nationally managed rivers is:
▽ "Kaigen River" flowing through Kagoshima Prefecture
,
▽ flowing through
Miyazaki Prefecture and Kagoshima Prefecture "Kawauchi River", "Oyodo River",
▽
"Komaru River",
which flows through Miyazaki Prefecture, "Gokase River,"
▽
"
Kuma
River,"
which flows through Kumamoto Prefecture.
Moreover, in Kyushu, there is a risk of flooding at other rivers managed by the state, where there is a risk of rainfall equal to the amount of rainfall that is the standard for building dikes.
In addition to large rivers, we are calling for caution as there is a high risk of flooding in small and medium-sized rivers.
Even in Typhoon No. 19 last year, the amount of rainfall in the basin of the Chikuma River, Abukuma River, and Kuji River exceeded the standard for developing dikes, etc., and the river dike actually collapsed or water overflowed beyond the dike. The damage was one after another.
