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 concerns, 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.

5.1 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.

5.2 The criteria will address only the collection of data on noncohesive sediment. A noncohesive sediment is one that consists of discrete particles and whose movement depends on the particular properties of the particles themselves (1). These properties can include particle size, shape, density, and position on the streambed with respect to other particles. Generally, sand, gravel, cobbles, and boulders are considered to be noncohesive sediments.
