HM 161.29 Sluice Gate Show data sheet (pdf file) Print page
Technical Description
The undershoot weir is one of the adjustable forms of weir, the water passes underneath the weir gate. The moveable weir is fitted to a base that sits on the floor of the channel and is bolted in position. In practice, these simple to construct and thus economical undershot weirs are used to obtain a constant flow from a varying water level. For exact measurement of water levels, the use of the HM 161.52 Level Gauge on the moving HM 161.59 Instrument Carriage is recommended.
Learning Objectives / Experiments
Observation of the flow under an undershot weir:
- Observation of hydraulic motion on discharge
- Observations on the movement of upper rollers
Relationship between dam height and discharge
