HM 160.33

Crump Weir

Technical Description

The crump weir is a fixed weir. In the normal case, the water flows over the weir without the down-stream level being below the weir crest. If this is the case, such a weir is termed an underwater weir. The experimental set-up is placed on the base of the flume and fixed in place with a bolt. The weir body is made of plastic. Tubular seals inserted in slots on the weir body complete the experimental set-up. In practice, crump weirs are used as so-called submerged dikes.

Learning Objectives / Experiments

In conjunction with the HM 160, the following experiments are possible:
· Discharge processes on an underwater weir
· Flow and supercritical flow states
· Amount of energy in flows in open flumes

For the exact measurement of water levels, the HM 160.52 Level Gauge is recommended.

Features

· Flow behaviour on an underwater weir
