The aim of this study is to define the condition of realizing the interregional water transfer in the case of the Ohgo-Yamada canals in Meiji and Toban Irrigation Project in the Banshu Plain, Hyogo Prefecture, the most concentrated area of farm ponds in Japan.The result follows:Regarding the water transfer from the Ohgo-Yamada River, water right of the lower stream area, such as mill compensation as source measure and restriction of the irrigation term, besides techniques and capital, was a determining factor for its realization.The realiztion of the Toban Irrigation Project is considered to have been determined by the Kakogawa weir as source measure and the reservoir compensation for the Dondo Dam. In other words, this Project consisted in regulating the drawing water quantity of both Gokai and Uwabei weirs from 25 m^3/s to 8 m^3/s by integrating them at the Kakogawa Large Weir. But the associations of both weirs could only agree to the Project When modern techniques, governmental aids to expenses to the present works and compensation works for canal improvement.To conclude, interregional water transfer may be realized if a series of water-use regulations concerned are planned to reconcile the actual advantages and disadvantages regarding water right.
