The design approach of the drainage system has limitation not to consider the extreme rainfall condition of which I-D-F curve is non-stationary by climate change and variability. Therefore, the assumption that the I-D-F curve is stationary to design drainage system maybe not available in the climate change, because climate change has changed the characteristics of extremes rainfall event to be non-stationary. In this paper, design rainfall by rainfall duration and non-stationary I-D-F curve are derived by the conditional GEV distribution. Furthermore, the effect of design flood discharge with increase of rainfall intensity was analyzed by distributed rainfall-runoff model, S-RAT. Although there are some difference by rainfall duration, the traditional I-D-F curves underestimates the extreme rainfall events for high-frequency rainfall condition. As a result, this paper suggests that traditional I-D-F curves could not be suitable for the design of drainage system under climate change condition.
