Restoration of Yodo River (Osaka City, Osaka)

In Yodo River running through Osaka, earth and sand are deposited around the spur dike, which was built to maintain the course for cargo ships, and many pools and valuable habitats for organisms have been created. However, because the water level fluctuation has decreased as a result of the construction of Yodo River Great Weir downstream, its environmental impact on Johoku pools is a concern.
For this reason, an experiment toward the recovery of the pool environment is being conducted by improving the operation of the weir to increase the water level fluctuation and improve the in-pool water quality.
