Sampling surface and subsurface particle-size distributions in wadable gravel- and cobble-bed streams for analyses in sediment transport, hydraulics, and streambed monitoring

, : Sampling surface and subsurface particle-size distributions in wadable gravel- and cobble-bed streams for analyses in sediment transport, hydraulics, and streambed monitoring. General Technical Report Rocky Mountain Research Station, USDA Forest Service (RMRS-GTR-74): xvii + 428 pp.

This document provides guidance for sampling surface and subsurface sediment from wadable gravel- and cobble-bed streams, intended for use in US national forests. After a short introduction to stream types and classifications in gravel-bed rivers, the document explains the field and laboratory measurement of particle sizes and the statistical analysis of particle-size distributions. Analysis of particle parameters, including shape, density, and bulk density is also discussed.
