内容注記	Other The model parameters for flood prediction currently used by river management have been established based on the relationship between precipitation and runoff for only a few specific cases. The prediction accuracy can be low when the data of cases that differ from the specific cases used for parameter-setting are applied, even when the subject cases are from the same basin as the specific cases. In this report, to improve the flood prediction accuracy of river management, a technique to calculate the run off rate corresponding to the basin storage capacity, which represents the wetness/dryness of the basin, was introduced by quantifying the basin storage capacity. By using the newly developed technique, reproduction of hydrographs and simulations of flood prediction were done. The technique compared with the currently used technique in which the runoff rate is fixed.
