Helley-Smith Sampler

Helley-Smith stor

Application:
The United States Geological Survey (USGS) originally developed the Helley-Smith sampler, and it was designed for collecting sand, silt, gravel, or rock debris carried by streams above the seabed.

The sampler is a good choice for collecting bed load materials, which have a partial size or a density that does not allow great movement above or away from the streambed.

It makes it possible to define the rate at which dams can fill and thus improve the ecological continuity of water flows by allowing sediments to be sifted at the right times.

The chamber has a square opening of 64 cm² (8 x 8 cm).
