2 Implementation of EU Water Framework Directive (2000/60/EC) …

The bodies of water are represented by the water mass belonging to certain lakes
(natural or artificial), streams (river, channel, river sector), transitory waters and
coastal waters. They are differentiated through natural or anthropic characteristics.
The criteria used for the delimitation of bodies of water were the following: categories of surface water; the typology of surface waters; the physical-geographical
and hydromorphological characteristics of the basin; the pressures and the state of
surface waters; the limits of the protected areas. 3717 bodies of water were delimited, of which eight for the Danube Delta. The average length of bodies of water is
21.3 km. Out of the total, 37% are accounted for non-permanent bodies of water.
The average length of a body of water in Romania is 21.3 km, comparable with
the lengths within other Danubian countries: 26 km in Germany, 12 km in Austria,
17.9 km in Hungary, etc. [97].
A body of water must belong to only one category of water and, thus, it cannot
include a river and a lake. A body of water does not criss-cross the limits of another
body of water, and it must have the same quality. Confluence may represent the
limit of a surface body of water. The body of water must have the same quality
status (very good, good, moderate, satisfactory, unsatisfactory). The chemical and
hydromorphological pressures section the body of water into smaller bodies. The
river sectors on which hydromorphological alternations are recorded are the heavily
modified bodies of water. The anthropic intervention creates artificial bodies of water.
The protected areas of an aquatic nature represent independent bodies of water.
The environmental objectives for the surface waters, in conformity with Article
4 of the Water Framework Directive 2000/60 of the European Union are as follows:
– preventing the deterioration; protecting and restoring until achieving a good status
of waters;
– protecting and restructuring the artificial and heavily modified bodies of water in
order to achieve a good ecological potential and a good chemical status of waters;
– progressively reducing pollution.
The monitoring of surface waters is provided by specific methodologies
(Table 2.7).
The monitoring frequency for the protected areas that ensure >100 m
3 /day is
determined by the number of inhabitants ascribed to the centralized supply system
(Table 2.8).
The groundwater bodies are represented by an aquifer, several aquifers or a part
of an aquifer. They are monitored using the multiparameter electronic sensors. They
are identified based on the following criteria: geological (nature of the deposits, age,
structure); hydrodynamic (extension of the geological limit of the hydrographical
basin—for the phreatic); status (quantitative and qualitative). The bodies of water can
also be transboundary. The delimitation is only done for the aquifers with economic
importance (discharges exceeding 10 m
3 /day). The other aquifer deposits do not
represent bodies of water.
The process of identifying highly modified bodies of water is based on the biological data. Where biological data were not available, abiotic criteria were also used
for temporary identification of highly modified bodies of water. These are based
