文摘

We performed frequency analyses of urban extreme precipitation and runoff events. Many assumptions on extreme precipitation-runoff relationships are less valid. There is wide uncertainty ranges due to sampling variability. The uncertainty has a large effect on reliability of design and management. Extreme runoff process study is useful for design and management of infrastructure.
