What is BS 3680-10E - Sampling and analysis of gravel bed material about?
BS 3680-10E is an international standard that discusses the methods of sampling and analysis of gravel-bed material.
BS 3680-10E specifies methods for sampling surface and subsurface gravel-bed material and the analytical procedures to determine the size distribution of gravel-bed material in open channels.
BS 3680-10E applies to materials having diameters of 2 mm and over. In practice, gravel-bed material may consist of two components- A coarser layer on the surface and finer subsurface material. The surface material is particularly relevant to investigations of the initiation of bed material movement and flow resistance, while subsurface material is relevant to investigations of bed material transport. There are two sampling techniques applicable to graded gravel-bed material. One method is to collect a definable in situ volume of material which is subsequently dealt with as a bulk sample. The second method is to sample material from the surface using one of several procedures.
BS 3680-10E discusses these two methods separately and presents conversion factors that are derived from an idealized homogeneous material.
Who is BS 3680-10E - Sampling and analysis of gravel bed material for?
BS 3680-10E on sampling and analysis of gravel bed material is relevant to:
- Manufacturers of gravel-bed material
- Manufacturers and designers of open channel flowmeters
- Manufacturers of measuring instruments for sediment transport
- Oceanographers and river engineers
- Testing authorities
Why should you use BS 3680-10E - Sampling and analysis of gravel bed material?
Bed-material samplers are used to obtain samples of sediment from the bed of a watercourse. Information with respect to sediment sizes is required for estimating resistance to flow in open channels and, together with hydraulic data, for calculating bed material load and making morphological forecasts.
BS 3680-10E definitions that depict a user-friendly idea of the sampling and analysis process. BS 3680-10E discusses sampling equipment and procedures that ensure their reliability. BS 3680-10E guides with grid sampling, areal sampling, and transect sampling and helps with the grain size/frequency distributions. BS 3680-10E guides in determining the sample size as well.
Overall, BS 3680-10E is useful as it provides guidance on the measurement of liquid flow in open channels that can be beneficial for your business and can also help you to expand your business globally.
