To address this issue, we carried out an idealized analysis based on reasonable assumptions and derived equations for the estimation of the sampling mass applicable to gravel sediment by the sieving method, based on the probability distribution theory and using the φ value as the unit of grain size (Krumbein 1938; McManus 1963).These equations provide a …

Soils with a large quantity of gravel-boulders deposit pose several problems in investigation. The presence of large sized particles precludes the sampl- ing by the usual methods of soil sampling in the true sense. Tests on disturbed samples are likely to yield unreliable results, as the natural arrangements of the grains and matrix material ...
Aggregate materials—like sand, gravel, crushed stone, slag, and recycled concrete—provide bulk and strength to concrete or asphalt. Large aggregate quarries and sand and gravel pits are located around most populated areas because of the high cost of transporting aggregate. (In fact, the cost of transportation from the mine to the consumer may even be …

alternative sampling method. Shovels are inexpensive, easy to carry, and produce lighter samples (Grost et al., 1991). Studies comparing spawning gravel sampling methods are limited. Two systematic comparisons of spawning gravel sampling devices have been conducted, one under laboratory conditions
cable, the focus is on bed sampling for stream assess-ment and design. Site selection for representative sampling Sufficient sampling of the streambed should be con-ducted to determine the spatial variability, size, and gradation of the bed material. No simple rule exists for locating representative sampling sites or reaches.
