Flow in rivers, canals and coastal areas is often associated with sediment transport. Bed-load transport is the main transport mechanism. During bed-load transport, solids are moved along the flume bottom.
HM 163.72 enables experiments on bed-load transport and consists of a sediment trap and a bucket for sediment feed. The sediment trap prevents the sediment of entering into the pump or the flow meter of the experimental flume HM 163.
The near-bottom flow containing the sediment is fed into the trap, where the sediment sinks to the bottom and accumulates. The sediment-free water continues to flow into the outlet element. The sediment is manually removed and taken back to the feed. Sediment is removed via a gate valve that is locked with a blind flange.
HM 163.72 is not suitable for suspended load transport.
The sediment trap is mounted between experimental section and outlet element during the setup of the experimental flume. It is not possible to install the trap at a later date.
