Purpose of typology

The WFD requires to differentiate the relevant surface water bodies with respect to type and that Member States establish reference conditions for these types

The main purpose of typology is consequently to enable type specific reference conditions to be defined which in turn is used as the anchor of the classification system

Common Implementation Strategy

System A & system B For each surface water category, the relevant surface water bodies

within the river basin district shall be differentiated according to type. These types are those defined using either "system A" or "system B" identified in Section 1.2.

If System B is used, Member States must achieve at least the same degree of differentiation as would be achieved using System A. Accordingly, the surface water bodies within the river basin district shall be differentiated into types using the values for the obligatory descriptors and such optional descriptors, or combinations of descriptors, as are required to ensure that type specific biological reference conditions can be reliably derived

River typology in the Danube river basin district The typologies of the Danube tributaries were developed by the countries

individually. Stream types relevant on transboundary water courses were bilaterally

harmonized with the neighbors. Most countries in the Danube River Basin (Germany, Austria, Czech Republic,

Hungary, Slovenia, Croatia, Serbia, Romania, Bulgaria, Bosnia and Herzegovina) have applied System B. The Slovak Republic and Ukraine have used System A.

The common factors used mostly in DRB typologies are ecoregion, altitude, catchment area and geology. In the Czech typology the ecoregions are not included, instead of ecoregion, sea drainage area (= river basin) is used. In Slovenia no altitude classes were used in river typology.

Conclusions & recommendations (1)

Water body types may be differentiated using ”System A” or ”System B”;

The two systems are similar in that they contain the same obligatory factors: geographic position, altitude, geology, size and (for lakes) depth;

Optional factors of System B can be used as desired by Member States and can be complemented with factors other than those mentioned in the Directive

Conclusions & recommendations (2) The Directiveґs descriptors of geology (in System A) refer to the dominating character (calcareous, siliceous, etc.), expected to have the strongest influence on ecological quality of the water body;

The Directiveґs requirement that MS must achieve the same degree of differentiation with System B as with System A is interpreted to mean that if System B is used, it should result in no greater degree of variability in type specific reference conditions than if System A had been used. Hence, if a lower number of types, using System B, results in equally low or lower variability of reference conditions values as would be given by System A, this would be acceptable;
