Many lakes and inland seas all over the World
experience anthropic impacts of varying extent and
nature. The major forms of human pressure on
large inland water bodies are (i) pollution and
(ii) unsustainable diversions of water from tributary
rivers for irrigation and/or industrial uses.
Consequently, physical and chemical regimes of the
water bodies are often strongly affected, which is
manifested through desiccation, salinization,
eutrophication, oxygen depletion, sulphide
contamination, etc. The most well-known examples
include the Aral Sea, the Dead Sea, and many other
lakes in the global perspective. To a certain degree,
this also refers to enclosed and semi-inclosed seas,
such as the Caspian, Black, and Azov Seas, and even
some coastal areas of the ocean, especially those
adjacent to river estuaries. In many cases, such as that
of the Aral Sea and Lake Chad, for example, the
deterioration is forced by not only the anthropogenic
pressures, but also the climate change trends. It is,
therefore, important to distinguish the human impacts
from the natural variability.
Better understanding of the related physical and
chemical mechanisms can only be achieved through
correct coupling between the lacustrine (oceanographic)
dynamical phenomena occurring in the bulk of the water
bodies on the one hand, and estuarine and groundwater
hydrology processes and environmental flow conditions
in the catchment basins on the other.
This session is intended for observational, remote
sensing, and modeling studies quantifying different
aspects of this coupling, as well as various
manifestations of relevant anthropogenic impacts.
Reports of recent field measurements in the regions of
special interest are particularly welcome.
