| Research Abstract |
The achievements of this study are the technological development of the Paddy Field Dam(PFD), the quantification of its effect, and the propagation of the measure. We developed several types of runoff control devices for five agricultural reservoirs that have different drainage systems. As a result of the examination, it was confirmed that the PFD measure functioned effectively to mitigate inundation magnitude in all the study reservoirs. The economic values of the PFD are estimated to range between 1,000 and 17, 000 yen depending on the characteristics of reservoirs. Owing to the success of the PFD in Niigata, the PFD is practiced in Hokkaido, Toyama and Yamagata Prefectures.
