This episode, presented in Tamil, explores the coastal geomorphology of Kanyakumari District — the southernmost tip of the Indian peninsula where the Arabian Sea, Bay of Bengal and Indian Ocean converge. The discussion explains how marine processes such as wave action, longshore currents, tidal influence and sediment transport interact with geological structure and coastal lithology to shape distinct landforms including beaches, rocky headlands, cliffs, spits and estuarine features. Emphasis is placed on the dynamic balance between erosion and deposition and how seasonal monsoonal variability influences shoreline behaviour.
The episode further examines anthropogenic interventions such as harbour construction, coastal protection structures and sand mining, and their geomorphic implications. Using scientific interpretation grounded in coastal process theory and observational evidence, the programme aims to help students and research aspirants understand how coastal landscapes evolve over time. The content is delivered in clear Tamil while maintaining academic accuracy and conceptual depth suitable for Earth science learners.
