distance between the profiles was 250 m along the whole lower Danube. Additional
topographic determination on several dykes along the Danube where the situation
was critical, historical data regarding high and low water regime of the Danube and
so on. All this data served as calibration variables to get the most precise model at
that time.
Using the hydro-ameliorative schemas of the Danube Floodplain Polders, which
exist only in National Institute of Research and Development for Land Reclamation
Bucharest (ISPIF) archive, the consortium experts designed the new defense lines
and the economic objectives for this area—the flood and menace levels will correspond to the Romanian National Institute for Hydrology and Water management
(INHGA) objectives. The development strategies and programs for long-term land
use along with the macro-regional and globalization integrative processes have been
concentrated on the political program objectives to assure a durable development.

8.3.1 Hierarchy of Spatial Distribution of the Categories
of Ecological Equipotential Areas
The natural capital of the lower Danube floodplain has a productive capacity that
must be known by its functional cells to avoid degradation, destruction under anthropogenic impact and to favor the sustainable use of its support capacity. Ensuring sustainable socio-economic development in the Danube floodplain area is also based on
knowledge of ecological sustainability, ecosystem integrity, environmental sustainability, ecological, and regional ecosystem balance. The biological diversity, functionality and naturalness of the ecosystems in the floodplain of the Lower Danube is
a result of their evolution over time and the succession of the various “civilizations”
that have disturbed the balance of the components of the initial environments.
The pan-European strategy for the conservation of biodiversity and ecosystem
function has clear objectives, among which for Romania and especially for the
Danube Delta, the awareness and participation of local communities must occupy a
very important place. The equipotential ecological area corresponds to the geotope
in the taxonomic scale of natural environments elaborated by J. Richard in 1975. The
use of the overlaid analytical map method implies a first assessment of the hierarchization of ecological equipotential areas categories. The landscape individuality of
the lower Danube floodplain is based on the interactions established between three
main components: ecological potential (ecological support), biological exploitation and anthropic action. They provide the common dynamics of the geosystem
expressed through a certain type of landscape. Often, the dynamics of a component
may be different from the dynamics of the assembly, and then the change in the
relationships between the components imposes a new dynamic trend expressed by
