Gives guidance on the equipment and procedures for the sampling by quadrat samplers in waters of depth less than 500 mm, although methods are described to permit sampling, under certain conditions, in a water depth of up to 1 m. The procedures are applicable to all accessible aquatic habitats in rivers, streams and estuaries where current velocities in excess of 0,1 m/s would be expected.
