The Bed-Load transport in river training simulator (HI102) is designed to demonstrate the important phenomena of bed-load transport in the area near the bottom at subcritical discharge. The unit allows the observation of the formation of meanders and fluvial obstacle marks on structures.
- The unit is designed for the study of open-channel bed-load transport.
- The educational unit consists mainly of the stainless-steel experimental section, inlet element, outlet element, closed water circuit, 1 set of models.
- The closed water circuit include water tank, pump, and flow meter, the tank after the water drain contains a sediment trap with a filter element for sand.
- The flow meter is used to determine the discharge.
- The large dimensions of the experimental section enable the modelling of river courses with and without structure, the experimental section is supplied with grooves for plate weirs to achieve different flow conditions.
- The sediment is held in the experimental section by plate weirs at the inlet and at the outlet.
- In addition to bed-load transport in open channels without structures, some models can also be used to observe fluvial obstacle marks, namely scour formation and siltation at structures.
- The models supplied with the unit are three bridge piers, two islands, set of deflection plates which are inserted into the experimental section, these models can be configured to make another model.
- The educational unit is supplied with a movable instrument carrier and a point gauge which allows profile measurement in the sediment along the bottom and the determination of the discharge depth at each point on the experimental section.
- The main components of the educational unit such as the experimental section, inlet and outlet element are made of stainless steel.
- The sand grains are 1-2 mm in diameter
