Particle size characterizations of beach sediments along Thondi coast was carried out in the present study. The main objective of this work is to identify the textural behaviour of beach sediments and how wave energy correlates with grain size distribution. Grain size characteristics such as Mean, kurtosis, skewness and satandard deviation were estimated. The entire coastal area was characterized as well sorted, moderately well sorted and moderately sorted sediment environments. Sediments were identified as fine skewed to coarse skewed with platykurtic, mesokurtic and leptokurtic characters. Grain characteristics varied spatially and temporally along with beach orientation, foreshore slope with wave action and skewness correlates with shoreline changes. In some coastal tract having the negative skewness along the study region, but not very significant. The study depicts that the sedimentary coastal environment were influenced by the relatively medium wave action and some places were observed high wave action. From this study, it was concluded that the beach erosion, accretion, and stability of beaches are controlled by strong hydrodynamic and hydraulic process.
