Hydrometry — Suspended sediment in streams and canals — Determination of concentration by surrogate techniques

Hydrométrie — Sédiments en suspension dans les cours d'eau et dans les canaux — Détermination de la concentration par des techniques de substitution

Abstract / scope

ISO 11657:2014 specifies methods for determination of the concentrations and particle-size distributions of suspended sediment in streams and canals by surrogate techniques. ISO 11657:2014 covers brief description of the operating principle of each method and details of some of the instruments available.
