Textural analysis of surface sediments in Arasalar River, Tamil Nadu and Pondicherry Union Territory, India
S Venkatesan and SR Singarasubramanian
The studies on textural characteristics are valuable information to understand the source of evolution for sediments under river environment. In the present investigation surface samples were collected from Arasalar river and subjected to textural analysis. The phi values were determined and used to calculate the statistical parameters such as mean (Mz), standard deviation (σI), skewness (Ski) and Kurtosis (KG). It is found that the mean value varies from (0.667Ø to 2.367Ø), indicating that the size of the river sand is medium to fine grained nature. The standard deviation (sorting) indicates moderately well sorted to moderately sorted with a range of 0.478Ø to 1.042Ø, while the skewness values of the sediment samples ranges from -0.581Ø to 0.389Ø. The Kurtosis varies between 0.679Ø to 1.437Ø, indicating mesokurtic to leptokurtic nature. Linear discriminant values indicate that the sediments were mostly deposited as Aeolian process under turbidity environment. C-M plot inferred that Arasalar river sediments are dominantly characterized by rolling of transportation.
