This study has aimed at developing a method for economic evaluation of Paddy Field Dam, and strategies for maximizing its flood control effect for the propagation of the measure. The economic evaluation model calculates the flood damage mitigation effect generated by the Paddy Field Dam based on the result of inner water inundation analysis model, that is specialized in reproducing flooded water behavior in paddy field dominant basin. Furthermore, we developed multiple regression model to evaluate the economic value of Paddy Field Dam in a number of basins concisely based on the results of the aforementioned economic evaluation model. We finally indicated that the propagation of the Paddy Field Dam work needs governmental leadership, and it is important to prioritize basins to be invested to create better environment to maximize the effect of Paddy Field Dam work.
