| Abstract: | A
brief review of various physical processes acting in the Gulf of Kachchh
(GoK), which have prominent roles in Gulf dynamics, is presented in this
article. The eddies present in the GoK confirm that they are permanent features
of the GoK circulation. Accurate estimation of residual currents and eddies in
an active industrial coastal zone like the Gulf of Kachchh
is important because of its potential applications with respect to discharge of
pollutants. Though GoK is considered as a well-mixed system, recent studies
revealed that only the central Gulf is well mixed. Stratification in
temperature and salinity is noticed in the eastern Gulf, where a cold and high
saline tongue is observed in the subsurface layers. Model results indicated the
effect of seasonally changing winds the circulation. During southwest monsoon,
the predominant westerly winds enhance the flood currents by about 20% and
reduce the ebb currents significantly. In spite of semi-arid climate
and lack of major rivers flowing into it, the Gulf is highly turbid with
suspended sediment concentrations (SSC) during October-November 2002 ranging
between 0.5 mg l-1 and 674 mg l-1. |
