Standard Guide for Elements of a Complete Data Set for Non-Cohesive Sediments

SCOPE
1.1 This guide covers criteria for a complete sediment data set.
1.2 This guide provides guidelines for the collection of non-cohesive sediment alluvial data.
1.3 This guide describes what parameters should be measured and stored to obtain a complete sediment and hydraulic data set that could be used to compute sediment transport using any prominently known sediment-transport equations.
1.4  This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Guide for
Elements of a Complete Data Set for Non-Cohesive
Sediments
This standard is issued under the fixed designation D 5387; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
