Abstract
This paper presents the reproducibility analysis of the urban runoff model using several rainfall data, such as XRAIN and ground observation rainfall data, in the upper basin of Kanda river in Tokyo. XRAIN is known for its spacial high resolution, simulation with the original XRAIN data revealed a probability of lowering reproducibility for runoff analysis. On the other side, Urban runoff simulation using high density deployed ground observation rainfall data showed the hydrograph with the highest reproducibility among the simulation using other rainfall data. Instead, the corrected XRAIN, which considers the spatiotemporal characteristics of correlation with the ground observation rainfall data, indicated a possibility of improving the simulation hydrograph with high reproducibility.
