With a shortage of measured discharge data in the design basin,the design flood can be cal-culated by using the design rainstorm.With the gradual increase of extreme weather,in calculating the design rainstorm,attention should be paid to the influence of extreme heavy rainstorm around the basin on the design results to ensure the project safety.Analysis and calculation by rainstorm transposition method applied to the"9.3"extreme heavy rainstorm in Changhua show that the design rainstorm re-sults in the design basin are significantly larger,comparing with the design rainstorm without consider-ation of the impact from"9.3"extreme heavy rainstorm.The proposed rainstorm transposition method can provide reference for the planning and design of other similar projects in the future,and has popular-ization and application value.
