Cultivation changes in the paddy fields have an important impact on agricultural drainage planning. For deciding the dimension of agricultural drainage structures, the rainfall-runoff modeling quantifies the probable flooding that meets the drainage standards. This study aimed to propose an inundation damage-based method to determine the design drainage considering cultivation changes in the paddy fields. For this purpose, hydrographs were derived based on the rainfall-runoff modeling, and inundation damages were estimated utilizing three scenarios reflecting cultivation changes. Regarding the 48-hour design rainfall, it was necessary to determine the r coefficient of the Chicago method for design consistency. With the larger proportion of other crops in paddy fields, estimating inundation damage reduction would be more appropriate than the conventional flood-level-based design. The results of this study are expected to be considered as an alternative drainage design method under cultivation changes in paddy fields, while demonstrating further research to analyze the effects of the rainfall duration and the r coefficient on agricultural drainage planning.
