Textural characteristics and organic matter distribution patterns in Tirumalairajanar river Estuary, Tamilnadu, East Coast of India

Distribution patterns of grain size characteristics and organic matter in the estuary sediments of India from Tirumalairajanar river have been studied. The present study reveals that sediment texture is one of the main controlling factors for the distribution of organic matter. The sediments are mainly medium to coarse grained, moderately to poor sorted, fine skewed to coarse skewed and leptokurtic to mesokurtic in nature. Based on the CM pattern the sediment fall in rolling and suspension field. These textural parameters have been examined to understand hydrodynamics of the depositional environment.
