Hydrometry -- Measurement of liquid flow in open channels -- Methods of measurement of bedload discharge
This standard has been revised by ISO/TR 9212:2015
ISO/TR 9212:2006 reviews the current status of direct and indirect bedload-measurement techniques. The methods are mainly based on grain size distribution of the bedload, channel width, depth and velocity of flow. ISO/TR 9212:2006 outlines and explains several methods for direct and indirect measurement of bedload in streams, including various types of sampling devices.
