the excavation of these materials from the sea is frequently quite admissible, which
is important when other sources are not available on land. Therefore, a scientific
approach to the solution of the problems of the possibility, locations, and admissible
amounts of such material is important.
Using of the sea as the source for food resources led to the development of
special aquaculture farms in the coastal locations, which is most productive for
cultivation species of marine fauna.
Solution of the problems related to the ecology of the coastal zone is impossible
without the data on the hydrodynamic transport of sedimentation. Solid particles
transported by water flows may become absorbers of the chemical and radiation
pollution.
The role of the coastal zone in the human life and vital activity is not limited by
these examples. They are given here only to illustrate the many-sided nature and
importance of our interests in this part of the World Ocean. At the same time, the
anthropogenic factor becomes one of the most important in the dynamics of the
coastal zone. In addition, this part of the ocean is most vulnerable and sensitive to
various forcing, and the problem of protecting and conservation of the environment
is most pressing here. It becomes clear that the solution of the problem of the
possibilities and methods of the technical expansion should be preceded by a
forecast of its consequences. Such a forecast can be carried out on the basis of
specific knowledge and thorough analysis of the dynamic processes in the
coastal zone.
7.2 Lithodynamics of the Coastal Zone
In the last decades such terms as “lithodynamics”, “lithodynamic processes”,
“lithodynamic research” have become more and more spread in the hydrotechnical,
oceanographic, geo-morphological and geological publications. These terms define
the phenomena and research of sediment transport along the Earth surface due to
the exogenous factors and gravity. In the oceanographic science, these terms are the
most accustomed owing to the growing interest to such researches in the ocean.
Practical significance of these processes follows from the extensive human activity
on the sea floor from the coastal zone to the continental slope. Special departments
were organized in a number of scientific and design institutes to carry out
lithodynamic research considered as one of the major problems in the study of
the world ocean.
Nowadays, the Earth’s landscapes are involved into the lithodynamic research.
These investigations are carried out by various specialists: geologists, hydrologists,
hydrotechnicians, geomorphologists, and lithologists mostly with the aim of solving particular applied or scientific problems. A number of monographs appeared
which are fully or partially devoted to the lithodynamics of some landscapes
deserts, fluvial valleys, sea coastal zone, mountain slopes. Until very recently,
research of fluvial processes has been most successful and intense.
