Hydrometry. Suspended sediment in streams and canals. Determination of concentration by surrogate techniques Ingestion-build-189776 PD CEN/TS 17313 describes real1 Scope This International Standard specifies methods for determination of the concentrations and particle size distributions of suspended sediment in streams and canals by surrogate techniques. Methods based on bulk optical principle of water such as transmission and nephelometry are the most commonly used surrogates for determining suspended sediment concentrations (SSC). Instruments and techniques based on acoustic attenuation and or acoustic
