Seasonal changes of the sediment size distribution and stability along the beaches of Kerala, south west coast of India

216-220Mean grain size distribution under different environmental conditions along the coast of Kerala showed considerable spatial variation (0.14-0.96 mm). Standard deviation values indicated a very well sorted class along all the beaches with a lowest value of 0.48 phi. Difference in standard deviation values between the stations were significant in all the stations, Samples were nearly symmetrical to negatively skewed with most of the values clustered at -0.01 to -0.10
