HM 162.32

DESCRIPTION

Technical Description

Ogee-crested weirs are fixed weirs and form part of control structures. A flow transition to supercritical discharge occurs during flowing over the weir body. At the end of the weir downstream side, the supercritical discharge has a high flow energy. The excess part of this energy can cause damages. Therefore, energy should be dissipated, e.g. using a ski jump as weir outlet or a stilling basin.

HM 162.32 contains an ogee-crested weir with two different weir outlets (chute only and chute with ski jump).

The optionally available accessory HM 162.35 contains elements for energy dissipation to study further ways of energy dissipation.


Learning Objectives / Experiments

- effect of the weir outlet on flow processes
  * chute
  * chute with ski jump
- position of hydraulic jump depending on downstream water level
 
together with a water level and a velocity meter:
- determination of the sequent depth
- determination of discharge and head
- comparison of the theoretical and the measured discharge
