Liquid flow measurement in open channels — Sampling and analysis of gravel-bed material

Mesure de débit des liquides dans les canaux découverts — Échantillonnage et analyse des matériaux du lit graveleux

Abstract / scope

Applies to surface and subsurface material having diameters of 2 mm and over. Two sampling techniques are applicable: one is to collect a definable in situ volume of material which is subsequently dealt with as a bulk sample, the second is to sample material from the surface, using one of several procedures.
