  3. WFD Cycle 2 morphology classification

WFD Cycle 2 morphology classification

Summary

This dataset is a subset of the "WFD Classification Status Cycle 2" dataset and contains summary data for the element morphology as used in the classification for Ecological status for the water framework directive (WFD). Morphology classifications are assessed and reported on a High, Supports Good or Does Not Support Good basis. Water bodies will only be classified as High if they have morphological conditions that reflect totally, or nearly totally undisturbed conditions. These conditions include continuity, width and depth, structure and substrate of rive bed and structure of the riparian zone for rivers; depth, quantity, structure and substrate of lake bed and structure of lake shore for lakes and depth, quantity structure and substrate of bed, structure of intertidal zone and wave exposure for estuaries and coasts and direction of dominant currents for coast only.

Lineage

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
