Criteria:
• Salinity
• Exposition
Water Body Types
![Page 6: TMAP – WFD Workshop Reference Values Hamburg 29 – 30 November 2004](https://reader038.vdocument.in/reader038/viewer/2022110210/56812c50550346895d90da00/html5/thumbnails/6.jpg)
Preliminary Designation:
Heavily Modified Water Bodies (HMWB)
Discussion in NL: Loss of salt marshes due to embankments: Wadden Sea as HMWB ?
• Transitional waters as „HMBW“ (Ems, Weser, Elbe, Eider)
• Coastal Waters as „Natural Waters“
Criteria:
• Hydro-Morphology significantly changed
• Human uses (shipping, harbor, drainage..)

Preliminary conclusions Draft Reports 2005 (RBD Ems, Weser, Elbe, Eider)
“Wadden Sea will probably not reach the environmental objectives / good status by 2015“
Assessment Ecological Status
Schiermonnikoog2005
Stade1997
Main reasons:- High nutrient inputs- High concentrations of specific pollutants
But: - Gaps of information / monitoring data - Lacking of reference values and quantitative
criteria
![Page 8: TMAP – WFD Workshop Reference Values Hamburg 29 – 30 November 2004](https://reader038.vdocument.in/reader038/viewer/2022110210/56812c50550346895d90da00/html5/thumbnails/8.jpg)
WFD Objective
„Good ecological status by 2015“
Assessment Ecological Status
Good ecological status is a condition in which:
- Biological quality elements show only slight deviation from the type-specific reference condition
- Physico-chemical elements are at levels capable of supporting the functioning of the type-specific ecosystem
![Page 9: TMAP – WFD Workshop Reference Values Hamburg 29 – 30 November 2004](https://reader038.vdocument.in/reader038/viewer/2022110210/56812c50550346895d90da00/html5/thumbnails/9.jpg)
Definition of Reference conditions
• A condition in which a water body has suffered no, or only very minor anthropogenic impacts to its hydromorphology, physico-chemistry, and biology,
• Can be in the past or the present,• Can be derived from observations, historical data or
modelling, or where necessary expert judgement,• Can be expressed as ranges.

Reference conditions – Work status
• Van der Molen (Ed.) July 2004: “References and classification tools for transitional and coastal waters”
– proposal reference values for 42 water types, – not yet tested, – “living document”
• Dick de Jong , 2004. Determination of Reference conditions for plants in coastal waters.
– development of “potentional GES”
• projects on national and EU level
• Others?
