- Abstract
Superstandard overland flow generalized computing method comes up to solve the channel flood calculation, which is influenced by urban terrain and consequently receipt more rainfall flood in ungauged region. This method used design storm as an exchange, analyzed the design storm in water conservancy industry traditional atlas and the design storm in municipal industry approved formula, compared the differences, explored the recurrence interval cohesion way of the two industries and finally conversed to the superstandard overland flood value. This research took the Xiaokongtong channel in Qingyang City, Gansu Province as an example, calculated three sections, including the tableland flood, superstandard overland flood and pipe network catchment flow, provided some theoretical reference values for the channel cases that took the superstandard overland flow into consideration but entirely rely on the urban storm flood model and achieved less effect from it.
