The purpose of this study is to clarify the comparative study of areal rainfall of rain-gauge data and high-resolution radar data in medium and small river basins. This analysis used QPE of C-band radar and X-band MP radar as areal rainfall of radar data. As estimated of areal rainfall of rain-gauge data, this study has divided numbers of each watershed by Thiessen method. As a result of several analyses, areal rainfall of each radar data was similar to that of rain-gauge data. Areal rainfall
