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 slightly varying water level. For exact measurement of water levels, the use of the HM 162.52 Level Gauge on the moving HM 162.59 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
·
