Grain Size Analysis and Depositional Environment Condition along the Beaches between Ovari and Kanyakumari, Southern Tamilnadu Coast, India

Abstract

Textural analysis is the epicenter of any sedimentological research. Granulometric analyses of unconsolidated sediments are used as an index to decipher the depositional environment. The granulometric analysis display a significant fluctuation in mean size, sorting, skewness, and kurtosis due to the variation in wave energy and the extent of turbulence affecting the beach environment during the crosshore and alongshore movement of sediments. The present study is to document the variation in grain size distribution within foreshore sediments, i.e., between the high water line and the plunge point wherein the sediments are deposited under different wave energy conditions.
