Objectives of the study
Many small reservoirs in China were built in the 1950's to 1970's.Some problems have emerged With the operation for several decades,which have reduced of the flood discharge capacity and threaten the safety of relative structures and downstream residents, especially when the extreme storm is striking. In order to improve this situation, a light and easy to install technology which can significantly relieve the discharging pressure of the reservoir has been proposed,named siphon-type emergency flood discharging technology.
