The national government has carried out projects for flood control since “the River Act” was enacted in 1896, when Yodo River improvement work started. The civil engineer, who mainly made the plan and led the work was Dr. Tadao Okino. But Mr Johannis de Rijke, who was a Dutchman engaged by the national government of Japan, had already investigated Yodo River to make the plan. In this report, the comparison between the idea of Okino and that of de Rijke was studied. Okino adopted the peak flood discharge proposed by de Rijke as design flood discharge. Besides the floodway plan in the lower part of the basin in Osaka Prefecture was laid by de Rijke. However we found the large difference between the two plans. That was how to deal with the retarding basin in the middle part and Biwa Lake in the upper part of the basin. Okino constructed the intake weir in the channel out of Biwa Lake and changed the retarding basin into the protected lowland.
