Abstract:
Determination of Grain size analysis of beach sediments along location of kameswaram is studied. For this purpose, mean, standard deviation, skewness, and kurtosis were calculated from the cumulative curves to study the depositional processes. Environment of deposition was studied. Mean size and standard deviation distribution clarifies this observation. Presence of fine sand and well sorted to moderately well sorted nature of sediments. The inclusive graphic skewness (ski) indicates that they are fine skewed to coarse skewed; hence the sediment points to unidirectional transport (channel flow). The kurtosis (Kg) varies from platykurtic to very platykurtic nature. Linear discriminant functions of sediments indicate an Aeolian processes was dominant for the deposition of the fine grained sediments in shallow agitating water from the beach. Based on CM (coarser one percentile value in micron) pattern the sediments fall in rollring and suspension field. The significance of the present study is mainly focused on sedimentological characteristics of the pit samples are vertical size distribution, depositional process, environments and energy conditions of the deposits.
