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.
Abstract
Overview
ISO 11657:2014 - Hydrometry - specifies standardized methods for determining and using non‑sample surrogate techniques. The standard describes the operating principles, instrument types, measurement principles and limitations for optical and acoustic surrogates used in continuous monitoring of sediment in streams and canals.
