Abstract:
Environmental persistence, fate and interactive effects with living
organisms - beneficial or toxic - of trace elements are directly related to the
physico-chemical forms in which they occur. Knowledge on the association of
trace metals with different environmental compartments in an aquatic system
are, therefore, essential for monitoring the trace metal pollution as well as
transport, fate and bio-geochemical cycles of trace metals. This thesis is a
modest attempt in assessing the trace metal levels and their behaviour in the
aquatic environment of Kuttanad, an aquatic system that is severely affected
by man's intervention on natural processes, by seriously evaluating the levels
of trace metals in dissolved and particulate phases and also in the different
chemical fractions of the sediments.

Abstract:
This thesis attempts to gain insight on the mathematical approach to estuarine
oceanographic systems; also to closely understand the governing processes in the
estuarine environment as well as in the adjoining river reaches.
The main aim was to conduct pollution routing for tropical estuarine environment
namely, for the Cochin estuary. In this context, attempts have been made to apply,
verify and validate the application of models, pre- prepared with necessary
modifications to suit the area of interest by use of RIVMIX and WASP tools.
Finally the thesis concludes by highlighting the advantages and limitations in
modelling water bodies and concurrentlysimulates most of the possible scenarios
within the purview of this work.

Abstract:
Ecology is the study of systems at a level
in which individuals or whole organisms may be
considered elements of interaction, either among
themselves, or with a loosely organised environmental
matrix. Systems at this level are named
ecosystems, and ecology, of course, is the biology
of ecosystems" (Hargalef, 1968).
This thesis includes principally, a study on
the ecology of zooplankton of the Cochin backwaters
conducted during the years 1971-72. This monsoonal
estuarine system is particularly interesting, since
it exhibits a wide range of variations in its environmental
conditions which is naturally reflected in
the fauna also. Several publications on various
aspects of its hydrobiology have come out in the
recent past. But studies on the zooplankton of the
estuary have mostly been discontinuous either in space
or time or restricted to its groups
