| Abstract: |
Surface sediment samples of the Kayamkulam
lake, located within the Quaternary geological province in the southwest coast
of India,
have been studied for textural characteristics. Lake bed is composed of a wide
spectrum of sediment types, viz: muddy sand, silty sand, clayey sand, silt,
sandy mud, sand, sandy silt and mud. Most of the sediment samples are of medium
to very fine grained, moderately sorted, negatively skewed and mesokurtic
sands. CM pattern shows that the sediments are transported mainly by suspension
and rolling. Textural parameters together with the CM pattern indicate the
prominent role of ebbing and flooding in changing the characteristics of
sediments in the Kayamkulam lake, especially in the estuarine mouth and
adjoining areas. Present study reveals that hinterland drainages play
significant role in changing the textural characteristics in the northern and
southern arms of the lake.
