ِِDischarge Coefficient in Oblique Side Weirs

2007
Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels.

THE EFFECTS OF CURVATURE IN SUPERCRITICAL SIDE WEIR FLOW

Journal of Hydraulic Research, 1983
A method for analysing supercritical flow in a channel fitted with a side weir has been developed and tested against experimental data. Results of the experimental programme have established the conditions under which supercritical flow occurs along a side weir, and showed that in cases where the flow upstream of the weir is subcritical the draw-down ...

Spatially Varied Flow over Side-Weirs

Journal of the Hydraulics Division, 1972
An experimental investigation of the flow over sharp edged side-weirs in rectangular channels is reported. The experiments cover subcritical and supercritical flow regimes with weirs of zero as well as finite height. The subcritical flow experimental data agree well with the derived analytical expression for the variation of the De Marchi coefficient ...

Supercritical flow over a rectangular side weir

Canadian Journal of Civil Engineering, 2003
Side weirs are flow-diversion devices widely used in irrigation, land drainage, and urban sewage systems. Hydraulic characteristics of a sharp-crested rectangular side weir under supercritical flow have been studied in this paper. The concept of elementary discharge coefficient for supercritical flow is introduced. The elementary discharge coefficient

Flow Characteristics of a Side-Weir in Rectangular Channel

Journal of Korea Water Resources Association, 2002
Flow characteristics occurring a side-weir overflow in rectangular channel is investigated in this study. A numerical model based on the two -dimensional shallow-water equations is employed to review the factors influencing on the side- weir overflow discharge and the change of flow depths and velocities.

Computer Programming for Flow over Side Weirs

Journal of the Hydraulics Division, 1973
A procedure is presented for computing water surface profiles and discharge in an open channel with flow over side weirs. There is little restriction about the channel shape, variation of invert slope, convergence of the channel along the length of weir, etc.

Hydraulics of flow over side weirs [PDF]

, 1975
This thesis reviews the present state of knowledge of the hydraulics of flow over side weirs, and describes an experimental investigation into the flow of water over side weirs using a laboratory flume. A detailed exeimination is made of the assumption conventionally used by many investigators that the total energy of the flow remaining in the channel ...

Supercritical Flow in Circular‐Shaped Side Weir

Journal of Irrigation and Drainage Engineering, 1994
The flow features of a side weir in a prismatic circular‐shaped channel as used in sewage and irrigation systems are considered. The complex cross‐sectional channel geometry is simplified, and a generalized de Marchi equation is presented for the free‐surface profile.
