2. Description of the Related Art Conventionally, research on rivers has been carried out sufficiently for various purposes over many years. At one time
In one area, research on the use of river water was undertaken in relation to agricultural work, and made a significant contribution to agricultural technology and agriculture economy. Further, when there is a large amount of water in a river, various studies have been conducted on the transportation of services and goods to travelers or tourists by water transportation by utilizing the large amount of water. However, if the amount of water in the river increases abnormally due to long rain or storm, it cannot be maintained by the existing levees, causing flooding of the rivers, often causing the dikes to collapse. Therefore, various efforts have been made to discharge a large amount of water generated by long rain or storm from the discharge channel to the sea. However, when the tide is high, the water level in the river becomes high, and the levee is likely to break at that time. Therefore, in order to strengthen the banks of rivers, concrete structures have been used instead of natural soil. On the other hand, on the embankment of a river with a concrete structure, unlike the former bank, there is no part of the soil, and plants grow there and insects stay there to maintain the natural environment. ,about,
It's getting far apart.
