Description 29-34
The study was conducted up to 15 km upstream in the Beypore estuary of the
Chaliyar river in Calicut.
The study area was divided into four sections (5 km interval) with two
transverse stations on either side of each section. The logarithmic values of Richardsons number (log RL)
shows high variation at river mouth section of the estuary (section-I) and at
about 10km upstream (section-II) during the postrnonsoon period. During the
premonsoon period there was no noticeable variation in log RL values
at section-I and section- II and the estuary was found to be well mixed. During
the monsoon period the stratification was higher and the variation in log RL
was high from flood to ebb tide. The lower part of the estuary is a turbidity
maximum zone, especially during premonsoon season. During the postmonsoon
period the concentration of suspended matter was not high compared to
premonsoon and monsoon period. There was a high surface value during ebb tide
in monsoon period.
