Abstract

Some aspects of the estuarine oceanography of the Vembanad lake between
Cochin and Azhikode are discussed. Since this part of the lake is in confluence
with the Arabian sea at its southern and northern ends, at Cochin and
Azhikode, its circulation pattern and other characteristics are different from what
they are between Cochin and Vaikom. Because of the position of these two
mouths, which are exposed to the same tidal cycles, the high tides and low tides
each producing two opposite flows respectively converge and diverge leaving a
null zone, almost free of the tidal effect, around Kadakara, situated midway
between Cochin and Azhikode. Another significant feature of this pairt of the
estuary is an extreme low-salinity i«gion between Karthedam and Cherai during
monsoon and early postmonsoon, brought about by the deflected waiters of the
Periyar, opening at the northern end of the estuary
