Grain size and depositional pattern of sediment from Arasalar river mouth (ARM North and ARM South) in Karaikal region of Pondicherry Union territory and Southern part of Tamil Nadu have been carried to using the textural parameters. The samples were processed and sieved following standard procedures. Textural parameter like mean, standard deviation, skewness and kurtosis are calculated using standard methods to understand the transportation and the depositional environment of the sediments. Statistical parameters revealed that sediments are dominant in fine sand category, moderately well sorted, fine skewed to near symmetrical and falls under mesokurtic to platykurtic character. Linear discriminate function (LDF) value indicates that sediments deposited under aeolian and shallow agitated water process under Sh Marine and turbidity environment of the basin. CM diagram (C = one percentile in microns, M = medium in microns) of ARMN and ARMS sediments suggests that deposition was dominantly by bottom suspension and rolling..
