SARAVANAN, S  and  CHANDRASEKAR, N. Potential littoral sediment transport along the coast of South Eastern Coast of India. Earth Sci. Res. J. [online]. 2010, vol.14, n.2, pp.153-160. ISSN 1794-6190.

In the nearshore zone ofpresent study area, the movement ofsand alongshore is due to the action ofwaves and currents. The sediment movement along the shoreline ofstudy area is mainly governed by the forces associated with the incoming wavesandtheavailabilityofsedimentswithinthearea. Thepresentinvestigationhasbeenmadeasanattempttoappreciate the sediment movement in relation to wave activity along the coast. The longshore sediment transport is higher in the northerly direction as compared to southerly direction. The normal condition is for and to be moved annually or more frequently in the shallows and on the beach. Waves and wave-driven currents cause longshore drift ofsand alongthe beach and offshore. The net erosive nature of the study area (except Kanyakumari) from March to October is due to the prevalence ofhigh waves from S and SE directions.
