Survey and analyses of the coastal environments and beach materials from the Kasaragod coast of Kerala and Harnai of Maharashtra revealed the various surface structures on the intertidal sand flat that are the characteristics and indicatives of wave influence. Conical dome-like bioturbation structure formed by the Olivancillaria species, a marine macroinvertebrate, on the intertidal zone of Kasaragod has a significant role in reproducing the beach morphology. Typical notches and honeycomb structures, sand bars, and steep sea cliffs characterize the beach processes of Harnai of Konkon coast. Such physical and biological processes, important factors to differentiate the sea beach morphology, are observed and examined from the study areas of Kasaragod coastal zone of Kerala and Harnai of Konkon coastal stretches along the western coast of peninsular India.
