| Summary: | 碩士 === 國立成功大學 === 水利及海洋工程學系碩博士班 === 92 === The manhole (or junction box) in the sewer system is same the suddenly continuous expanded and contracted cross-section in the short distance of channel. In order to design the sewer system, effect on the flow due to a series of the suddenly continuous expanded and contracted cross-section in the prismatic channel is studied by the theoretical analysis and the hydraulic experimentations.
The backwater effect due to the suddenly expanded cross-section will make upstream depth higher than the normal depth. The hydraulic jump and the cross wave are induced by the separate phenomena on the downstream of the suddenly continuous expanded and contracted cross-section. The depth of both the suddenly continuous contracted and expanded cross-section and the upstream reach also will be increased by the choke due to the separate phenomena.
