Outline of Final Research Achievements

Lack of freshwater is a major social problem. Therefore, we investigated the floating dam reservoir method which is several hundred times as large as the conventional onshore dam. It was confirmed that it is effective to accumulate freshwater flowing from rainfall and river to the sea in floating reservoir dam. The dam will store water and float in the sea, but since it does not move, there are few restrictions on the shape. Also, since there is no pressure difference between the inside and the outside, it is possible to reduce the strength of the structural material, and it was confirmed by calculation that a simple partitioning of the polymer material is sufficient.
