It was found that the amount of sediment that flowed into the Yatsushiro Sea in Kumamoto Prefecture due to record-breaking heavy rainfall reached approximately 400,000 cubic meters around the Yatsushiro Port alone. Since the depth of water will become shallow due to the accumulated sediment, which may hinder the operation of cargo ships, the government will proceed with the removal of sediment in the future.

In the Yatsushiro Sea, where the Kuma River in Kumamoto flooded, flows into the Yatsushiro Sea.

The Ministry of Land, Infrastructure, Transport and Tourism conducted a survey on the condition of sedimentation around the Yatsushiro Port using a survey ship, and found that the amount of accumulated sediment was at least 400,000 cubic meters, equivalent to 80,000 10-ton trucks.

According to the Ministry of Land, Infrastructure, Transport and Tourism, a recent flood caused a large amount of sediment to flow into Kure Port in Hiroshima Prefecture even in the heavy rains of western Japan in 2018.The amount at that time was about 10,000 cubic meters. It means that there is no such thing.

Due to the accumulation of sediment, there is a place where the water depth is about 1 meter at the port where the ship is anchored and around the route, which may hinder the operation of a large freighter ship that transports livestock feed at Yatsushiro Port. There is.

The Ministry of Land, Infrastructure, Transport and Tourism wants to proceed with the removal work as soon as possible after discussing with Kumamoto Prefecture how to secure a disposal site for the removed sediment, but it may take about one year to completely remove it. Is that there is.

The Ministry of Land, Infrastructure, Transport and Tourism said, "The major issue is how to secure a place to dispose of sediment with an unprecedented amount of sediment. It will have a great impact on the local economy, and we would like to take immediate action." Talking
