In the present work, we generalize the results of our investigations in the field of simulation of
hydrophysical and ecological processes in coastal regions of various seas and some closed ba-
sins. The developed and applied mathematical models and the results of numerical experiments
are briefly analyzed.
Current advances in the field of oceanology are connected both with the creation and application of new
methods and equipment for marine observations and with the development of numerical simulations. Since any
experiment must be reproducible and (desirably) controllable which is practically impossible in the case of in-
situ investigations, the advantages of numerical experiments simulating the processes whose direct observation
is impossible are evident.
Logical trends in the development of science and current needs of the mankind led to the necessity of con-
centration of efforts of the researchers on the investigation of the dynamics of waters in coastal and shelf zones
of oceans and seas. The sea shelf occupies about
of the water area of the World Ocean but more than a half
of the mankind permanently lives in a narrow
200-km-wide coastal strip. As a result, the anthropogenic load up-
on the coastal water areas is quite intense and rapidly increases in the last decades. This, in turn, results in nega-
tive changes in marine ecosystems and the rate of these changes can be quite high. The anthropogenic influence
caused by the extensive, uncontrolled, and technologically poor development of the industrial and agricultural
infrastructure of the coastal territories is often connected with introducing new species and quantitative and qual-
itative violations of the natural cycles of circulation of nutrient substances and may lead to catastrophic changes
in the existing natural balance. Prospects of the commercial exploitation of the shelf zone and, in particular, its
use for the production and transportation of gas and oil inevitably increase the probability of major accidents
connected with irreparable damage to the recreational and biological resources of the sea.
In the present work, we generalize the results of our investigations performed for the coastal regions of var-
ious seas by the methods of mathematical simulation in the form of purposeful numerical experiments.
The main aim of the authors is to develop interdisciplinary mathematical models combining a hydrodyna-
mic model, a model of transport of pollutants, and a chemicobiological model and capable of describing the
