objects of hydrodynamic and environmental modelling
OBJECTS OF HYDRODYNAMIC AND ENVIRONMENTAL MODELLING

Danubian Lakes

Black Sea Estuaries

Lake of Yalpug

Lake of Kitai (China)

Tuzla Group of Estuaries

Dnipro-Bug Estuary

Dofinovka Estuary

economic and ecological problems of the danubian lakes

Fall of water level below UMO (minimum water level)

in low-water years

1

Increase in water salinity to the levels in excess of the optimum values for drinking water use and irrigation in the summer period

2

Deepening of euthrophication, overgrowing with macrophytes, aggravation of water pollution at lowering of water level within a vegetation period

3

Instability in dynamics of ecosystem performance,

its environmental state and productivity in the years with low water

4

Necessity for perfection of plans of water-resource management with the ecological factors being taken into account

5

ECONOMIC AND ECOLOGICAL PROBLEMS OF THE DANUBIAN LAKES
slide4
ECONOMIC AND ENVIRONMENTAL PROBLEMS OF THE BLACK SEA ESTUARIES SUBJECT TO THE HINDERED WATER CYCLE WITH THE SEA

Shallowing of the estuaries in the years with low water

Strong fluctuations in water and salinity levels during a year

Water quality deterioration in the period of summer isolation (salinification,

deepening of euthrophication,overgrowing, hypoxia,contamination)

Instability in dynamics of ecosystem performance,

its environmental state, productivity, terms for fish-farming

Loss of balneological resource of the estuaries

Lack of plans for economic and environmental management

complex of mathematical models for determination of management strategy

1

Models for forming water-salt balance in water bodies, methods for estimation of balance equation constituents

Complex of Mathematical Models for Determination of Management Strategy

Numerical simulation models for build-up of water quality in water bodies and shelf marine aquatoriae (containing the sets of autopurification and eutiphication of waters)

Numerical hydrothermodynamic simulation models

sub models composing the applied model for build up of water quality
SUB-MODELS COMPOSING THE APPLIED MODEL FOR BUILD-UP OF WATER QUALITY

Three-dimensional hydrothermodynamic model, describing

and turbulent diffusion of admixture in a water environment

under various hydrometeorological conditions,

taking into account the morphological features of a basin

(bathymetry, configurations of the sides) and river flow

slide8

SUB-MODELS COMPOSING THE APPLIED MODEL FOR BUILD-UP OF WATER QUALITY

The set of self-purification, with which one calculates any

decreases in concentration of a polluting

substance at every particular spatial point

due to the combined action of various physicochemical,

chemical,biochemical, and biological processes

taking place in the marine environment

slide9

SUB-MODELS COMPOSING THE APPLIED MODEL FOR BUILD-UP OF WATER QUALITY

The set of eutrophication involving a system of mutually

coupled differential equations which describe

the biogeochemical cycles of biogenic elements,production

and destruction of organic substance, trophic connections,

and the dynamics of oxygen at any particular

point of water environment

features of hydrodynamic set of the model of water quality

Three-dimensional thermodynamic forecasting model, based on the use of «primitive» equations of hydrodynamics

1

implemented in the curvilinear on the vertical system of co-ordinates

2

can be utillized for reservoirs and seashelf aquatoriae the separate areas of which have a subgrid scale in one of the horizontal directions (mouths of the rivers, narrow channels, canals etc.)

3

FEATURES OF HYDRODYNAMIC SET OF THE MODEL OF WATER QUALITY
features of hydrodynamic set of the model of water quality1

provided with a set of adapting of hydrometeorological information from the borders of the crated area

4

makes it possible to devide total flows into constituents: wind, density, flow, and barotropic ones

5

makes it possible to reproduce spatio-temporal changeability of thermohaline structure of waters, fields of admixture, fluctuations of water level, three-dimensional field of flows and intensity of turbulent exchange within the temporal segments from a few days to the annual cycle
