DIN EN 16772
Water quality - Guidance on methods for sampling invertebrates in the hyporheic zone of rivers; German version EN 16772:2016

Title (German)

Wasserbeschaffenheit - Anleitung für Verfahren zur Probenahme von Invertebraten in der hyporheischen Zone von Flüssen; Deutsche Fassung EN 16772:2016

Overview

In this standard the hyporheic zone is defined as the spatio-temporally dynamic ecotone between the surficial benthic substrate and the underlying aquifer. Within the hyporheic zone, water, solutes and biota are exchanged with the stream above, the groundwater below and the saturated sediments lateral to the channel. The term "hyporheic zone" is applied to the physical habitat while the term "hyporheos" coined by Williams and Hynes in 1974 is used to describe the faunal community inhabiting it. Investigations of the hyporheic zone may also be needed more generally for catchment management, river restoration, site-based investigations or for research. Consequently, the purpose of any study should be carefully considered when selecting the most appropriate method for sampling the hyporheos, especially if the collection of water quality and associated sediment data is also required. In addition, the methods described in this standard may require modification to reflect local conditions. 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.
