Abstract
Estuarine mangroves give natural support to the protection of the riverbanks, due to their
accumulative nature. To study this effect, it is necessary to measure sedimentation rates under
estuarine mangroves. Sediment plays an important role in the storage and release of nutrient into the
water column, the mineralization of organic carbon deposits by various kinds of microbes. In association
with other parameters, the sediment is responsible for the variations in densities of majority of benthic
organisms. Regular monthly collections of bottom water and sediment were made for a period thirteen
months from January 2008 and January 2009 at five different study sites using the motorized outrigger
canoe. The present investigation encompassed collection of data pertaining to various aspects of
sedimentology. Sediment temperature varied from 25.100c to 30.450c. The pH ranged between 6.18 to
8.30. Organic carbon Varied between 2.06 to 29.45%, moisture content varied from 20.10% to 41.88.
Values of interstitial water content is varied between 1.60% to 30.95%. Wide variation in the percentage
composition of sand (28.45% to 80.10%), silt (12.78% to 54.28%), and clay (3.66% to 33.63%) was
observed.
