Closed sediment circuit

Flows in rivers, canals and coastal areas are often associated with sediment transport. Bed-load transport is the main transport. During bed-load transport, solids are moved along the flume bottom.

HM 161.71 considers the bed-load transport and consists of a suction lance and a pipe system with pump.

At the beginning of the experiment, a sediment bed is made in the experimental section without flowing water. Then, the water circuit is switched on. The accessory is automatically identified by the PLC. The sediment pump is operated via the touch screen of the PLC of HM 161.

The flowing water transports the sediment close to the bottom along the experimental section. This bed-load transport can be observed clearly.

The outlet tank of HM 161 is designed as sediment trap. The suction lance is inserted in the outlet tank. A pump delivers the mixture of water and sediment from the bottom of the outlet tank to the water feed of the experimental section.

HM 161.71 is not suitable for suspended load transport.

HM 161 can be extended with HM 161.71 at any time.
