Specifies methods for sampling of both noncohesive sandbed material and cohesive bed materials, and sampling procedures to determine the size distribution of bed materials in open channels.

This Part of BS 3680 gives guidance on methods for sampling of both non-cohesive sand-bed material and cohesive-bed material (both of which may contain some fine gravel) principally for the purpose of determining the grain size frequency distribution of the bed material in open channels.

NOTE Other publications of relevance to samplers and sampling techniques are listed in the bibliography in Annex A.
