HM 160.28

Spillway with Skijump

Technical Description

The spillway with skijump is a so-called fixed weir. The weir body is made of plastic and is locked in place in the measuring section using a bolt. The weir body is sealed to the side walls of the flume using tubular seals that are inserted in the slots on the side of the weir body. On passing the weir, the flow changes from the flow state to the supercritical flow state, the ramp at the end of the spillway ensures that the flow is gently returned to its original state. In practice, such weirs are used after long sections of gradient where the direct impact of the flow over an extended period would cause serious damage, e.g. due to erosion.

Learning Objectives / Experiments

In conjunction with the HM 160, the following experiments are possible:
· Observation of flow forms
· Observation of the throw of the water
· Generation of different flow states by damming the down-stream water

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