This sampler is used to measure bed-load of coarse sand and fine gravel in rivers and other water- courses.
Streamlined
The streamlined sampler is mounted in a frame and consists of a mouth followed by a basket of fine wire meshing (width of the mesh 300 mu).
The sharp decrease of the velocity in the wide sampling chambers causes the sediment material to settle there.
A tail fin mounted on the frame keeps the sampler in up-stream direction.
The results of the measurements are influenced by the shape of the bed (ridges, dunes, flatbeds, etc.).
For a successful measurement knowledge of the relief of the bed is essential. The sampler can be discharged on board using the sample trough.
Benefits Bed-load transport meter Arnhem type
- Samples rolling course sediment and gravel rolling on the river bottom
- Mouth permits water and fines to flow through
- The mouth shaped to keep initial water speed
Availability
The set comprises the sampler, the bed-load transport meter frame with stabilising tail fin and lever and the sample trough.
