This European Standard provides guidance on methods for sampling invertebrates in the hyporheic zone of wadable rivers. It describes each method, including details of the equipment involved and its use in the field. Guidance is given on developing a sampling strategy and selecting an appropriate survey technique for the purpose of investigation.
