EXECUTIVE SUMMARY
In the countries of the Danube River Basin District (DRBD) different stream typologies have
independently been developed for the implementation of the EU Water Framework Directive (EU
WFD). The development of the typology systems as well as the attribution of water courses to
stream types followed the national needs within the scope of interpreting the EU WFD
specifications.
In order to prepare a stream type map of an international river basin, a synopsis of all relevant
national stream types is in demand. The high number of national types requires harmonisation
efforts to reduce the total number of stream types. Similar types defined by several countries
need to be identified and duplicate denominations have to be deleted. Harmonisation of national
stream typologies also plays an essential role in analogous mapping of the DRBD.
In this study stream types at rivers of the DRBD with catchment areas >4,000 km2 were
considered. The harmonisation of 157 national stream types resulted in a total number of 72
international stream types.
Due to missing data the ecoregions 6 Hellenic Western Balkan and 7 Eastern Balkan could not
be integrated in the analysis.
In summary, the particular ecoregions cover: Alps 14 types, Dinaric Western Balkan - 7 types,
Central Highlands 9 types, The Carpathians - 12 types, Hungarian Lowlands - 13 types, Pontic
Province - 10 types und Eastern Plains - 5 types. Furthermore, 2 stream types were specified as
"ecoregion independent types" that can occur in different ecoregions ("azonal types").
In Ecoregion 11 Hungarian Lowlands the harmonisation of stream types reduced the number of
types by one-third. Number of types in ecoregions 4 Alps, 5 Dinaric Western Balkan und 10 The
Carpathians were approximately halved.

1. INTRODUCTION
In the countries of the Danube River Basin District (DRBD) different stream typologies have
independently been developed for the implementation of the EU Water Framework Directive (EU
WFD). The development of the typology systems as well as the attribution of water courses to
stream types followed the national needs within the scope of interpreting the EU WFD
specifications.
In order to prepare a stream type map of an international river basin, a synopsis of all relevant
national stream types is in demand. The high number of national types requires harmonisation
efforts to reduce the total number of stream types. Similar types defined by several countries
need to be identified and duplicate denominations have to be deleted. Harmonisation of national
stream typologies also plays an essential role in analogous mapping of the DRBD.
Hence, a table of the national stream types is to be prepared as a synopsis of the national
typology systems, called "Table of Harmonisation".
The "Table of Harmonisation"
- sets fundamentals for a basin-wide stream type map,
- creates common basis for communication,
- facilitates transboundary monitoring issues,
- defines common types as basis for intercalibration.
The "Table of Harmonisation" covers all stream types at rivers in the Danube River Basin with
>4,000 km2 catchment area. This also includes stream types <4,000 km2 located at the
upstream courses of these rivers. The Danube river and its section types are not considered in
this study.
Data on the latest versions of the national typologies were collected and analysed with regard to
commonalities and differences. Most relevant for the typology comparison were the obligatory
parameters of the system A of the WFD (ecoregion, size, altitude, geology) and several optional
parameters of the system B, that were used in a comparable way in the national typology
systems e.g. sub-ecoregions and mean substrate.

2. BRIEF OVERVIEW OF NATIONAL STREAM TYPOLOGIES
For the harmonisation of national stream types at relevant rivers 13 countries provided most
recent information about stream typologies and descriptions of individual stream types (see
Table 1).
Data from Ukraine only covered the Tisza river. Moldavian information was confined to
descriptions of national types at the Prut river.

2.1. Ecoregions
The Danube River Basin District covers nine ecoregions or parts thereof (see Table 2). Some
countries have shares of several ecoregions, e.g. Austria and Serbia and Montenegro have parts
of five ecoregions on its territory in the DRBD. Ecoregion 11 (Hungarian Lowlands) has an
importance due to its location in the middle of the basin. Nine DRB countries have territories in
this ecoregion (see Table 2).

All national typology included ecoregional data to delineate stream types except for Serbia and
Montenegro. According to statements of national experts (M. Paunovic, email notice), the scale
on which ecoregion borders are generally defined is too large. In Serbia more precise maps are
required to include information on ecoregions in the national stream typology.

2.2. Stream Types
All countries in the Danube River Basin District applied System B according to Annex II of the
EU WFD. Besides System A parameters (altitude, catchment size, geology) additional
information about climatic, hydrological, morphological or biocoenotic characteristics was
available (see Table 3). These data partly covered typological factors of System B.
Countries adopted class boundaries of System A parameters following national requirements:
For instance, Austria and Slovak Republic included an additional altitude class for watercourses
higher than 1500 metres. Hungary established overlapping class boundaries of catchment area
in order to account for continuous changes in nature that do not stop at fixed borders. Serbia
and Montenegro defined an additional catchment area boundary at 4000 km²; Slovenia at 2500
km². Slovak Republic and Bulgaria introduced the class of "mixed" geology.

Most of the countries used data on mean substratum composition, mean water slope or valley
shape to characterise their national stream types more precisely. Croatia classified the mean
annual river flow [m3/s] in its national typology. Slovenia added information about lake outflow
influence and linmocrene spring influence to the parameter "hydrology/water flow". The
Romanian river types were defined regarding precipitation [mm p.a.] and temperature [°C]
amongst other parameters.

3. METHODOLOGY AND BASE DATA
3.1. Basic Considerations
- Objective: Harmonisation of all river types of the Danube River Basin located at rivers
with >4,000 km2 catchment area excluding the Danube River (see Annex 1)
- Descriptions of stream types differed among countries and available data on national
typologies was heterogeneous. Therefore, only System A parameters (ecoregion,
altitude, catchment area, geology) and respective parameter classes according to Annex
II of the EU WFD as the "least common denominator" were used in the harmonisation
exercise.
- In a first step, stream types were aggregated according to ecoregion, followed by
altitude, catchment size and geology.
- Stream types of Serbia and Montenegro could not be assigned to ecoregions and thus
were not considered in the harmonisation.
- If parameter values of System A corresponded among national types, these types were
merged. Therefore, Austrian types of various saprobiological basic conditions or
Hungarian types with different channel substrate were subsumed. Although altitude was
further divided within several national typologies, altitude classes of System A were
used in the harmonisation. Stream types covering different hydrological regimes were
also aggregated, e.g. for the Bulgarian typology.
3.2. Steps of Work
To develop a "Table of Harmonisation" for the stream types in the Danube River Basin the
following steps were performed:
1. Request for updating information on types of rivers relevant in the basin wide
overview
To ask for data about the latest version of national typologies, a template was established
and circulated. Countries were requested to note down as much additional information as
possible - also available data on types that were not used to officially describe the types
(For example, information on channel form is not used as a System B parameter in
Germany. But to establish the national typology, information about that parameter was very
useful).
Requested general information, obligatory factors of System A and further optional factors
of System B were:
- Code/abbreviation of stream type (with country code)
- Name of stream type (English)
- Name of stream type (national)
- Ecoregion
- Altitude
- Catchment size
- Geology (dominant type)
- Sub-ecoregion/bioregion
UMWELTBÜRO ESSEN / T. POTTGIESSER & S. BIRK
Harmonisation of DRB typologies
page 11
- Mean water slope
- Mean substratum composition (megalithal >40 cm; macrolithal 20 to 40 cm; mesolithal
6 to 20 cm; microlithal 2 to 6cm; akal 0.2 to 2 cm; sand and mud; silt, loam and clay)
- River discharge (e.g. <10 l/s; 10 to 300 l/s; 300 to 1,000 l/s; 1,000 to 10,000 l/s;
>10,000 l/s)
- Valley shape (canyon; V-shaped valley; meander valley; U-shaped valley; trough; plain
floodplain)
- Channel form (meandering; braided; anabranching; sinuate; ...)
- Hydrology / water flow (permanent, temporary, backwater, lake outflow influence,
limnocrene springs influence...)
- Other parameters
2. Preparation of an overview of all national stream types of the Danube River Basin
including type specific descriptions (national code, name, ecoregion, altitude,
catchment area, geology, mean substrate composition etc.) (see Annex 2)
3. Selection of data relevant for the "Table of Harmonisation"
Data analysis including selection and validation of criteria for the aggregation of national
types: Since descriptions of stream types differed among countries and available data on
national typologies was heterogeneous, only System A parameters (ecoregion, altitude,
catchment area, geology) and respective parameter classes according to Annex II of the EU
WFD as the "least common denominator" were used in the harmonisation exercise.
4. Merging of national stream types within the same ecoregion based on descriptions
of the abiotic conditions = Compilation of "Table of Harmonisation" for all national
types in the DRB
5. Design of a new trans-national stream type code for the DRB
For the harmonised stream types a "Danube River Basin type code" has been developed.
The Code is composed of a number combination, e.g. 10001)_122)_33):
1) 1000: for all stream types in the Danube River Basin according to the
,,RiverBasinDistrictCode" of the WFD-Code list
2) number of the ecoregion; "99" was assigned to the "ecosystem independent types"
3) consecutive number

4. "TABLE
OF
HARMONISATION" COMPARATIVE TABLES
OF NATIONAL STREAM TYPES IN THE DRBD
Within the harmonisation exercise the total number of 157 national stream types at rivers of the
DRBD with catchment areas >4,000 km2 were combined to 72 harmonised DRB-types (see
Table 5). In Table 5 the aggregated stream types are marked by a blue frame.
Due to missing data the ecoregions 6 Hellenic Western Balkan and 7 Eastern Balkan could not
be integrated in the analysis.
In summary, the particular ecoregions cover: Alps 14 types, Dinaric Western Balkan - 7 types,
Central Highlands 9 types, The Carpathians - 12 types, Hungarian Lowlands - 13 types, Pontic
Province - 10 types und Eastern Plains - 5 types (see Table 4). Furthermore, 2 stream types
were specified as "ecoregion independent types" that can occur in different ecoregions ("azonal
types").
In Ecoregion 11 Hungarian Lowlands the harmonisation of stream types reduced the number of
types by one-third. Number of types in ecoregions 4 Alps, 5 Dinaric Western Balkan und 10 The
Carpathians was more than halved.

5. Discussion

5. DISCUSSION
For the harmonisation of national stream types at relevant rivers in the Danube River Basin
parameters of the typology System A according to Annex II of the EU WFD (ecoregion, altitude,
catchment area, geology) and respective parameter classes according to Annex II of the EU
WFD were selected. This approach provided a high level of aggregation, e.g. relevant for
cartographic editing.
Gaps
Nevertheless, the compilation of the "Table of Harmonisation" remained incomplete due to
incomplete data about typologies of Moldova and Ukraine. In addition, the missing allocation of
Serbian types to respective ecoregions prevented further processing of Serbian data.
However, most likely the number of harmonised types will not increase significantly when
adding the information on national typologies currently lacking.
Prospect
Due to the differences in national typologies the aggregation of stream types based on
additional parameters such as mean substratum composition was not practicable. This approach
would have increased the total number of harmonised types, nevertheless it also would have
allowed for the assignment of biologically meaningful stream types on the international level,
e.g. to further facilitate the comparison of biological assessment results among countries.
However, the collected base data may serve this purpose on a smaller sub-basin scale.
Comparison: Table of harmonisation and intercalibration
The concept for harmonisation underlying this analysis differed from the approach followed in
the Eastern Continental intercalibration exercise. The latter aimed at defining stream types for
the intercalibration of biological classification schemes. Besides pooling of different ecoregions
and geology classes, channel substrates and more precise altitude classification were used to
assign common intercalibration stream types. These types covered various countries and
included different national stream types (or parts thereof).
The small to medium-sized mountain streams of the Carpathians (R-E1), for example,
correspond to the harmonised type 1000_10_8. Although Czech Republic, Hungary, Romania
and Slovak Republic took part in intercalibration of this type, 1000_10_8 only represents an
aggregation of Romanian types. Corresponding types of other countries are not located at
streams relevant to this study. The intercalibration type of large lowland rivers with mixed
geology (R-E3) embraces 10 harmonised types (1000_11_10 to 13 and 1000_12_6 to 11)
because of its combined ecoregional and geological characteristics.
