In this study, a distributed runoff model based on the surface runoff prediction model using the numerical solution of Richard's equation, the surface runoff model and saturated flow using the kinematic-wave method, and the unsteady flow model using the dynamic-wave method was proposed. This model allows calculations to be made for different infiltration characteristics in the study basin.<br>The digital elevation model consisted of nonstructural grids, and the hydrographic basin was divided into slope divisions and channels in this runoff model.<br>The calculation to obtain the runoff hydrograph was verified by actual hydrographs obtained by hydraulic monitoring at the newly tephra-mantled basin in Miyakejima volcano, which erupted in July 2000 and deposited thick fine-grained tephra. All the parameters of the soil properties of the deposited volcanic ash were obtained by laboratory and field tests.<br>The verification shows that the calculation results by this distributed runoff model show good accordance with the actual hydrograph.
