Coastal erosion is a major challenge for the people who are living along the west coast villages in Kanyakumari district. In the last two decades, the coast became vulnerable to erosion resulting loss of life and property. The interface of land and sea has also become fragile and show a gradual and continuous ‘accretion’ or ‘eroding’ tendency over a longer time scales, threatened the communities with this change of coastline. The Arabian Sea is usually rough during south-west monsoon (June-September) with waves as high as 10-15 feets with strong wind. Even though many causes influenced in erosion, strong waves are the prime cause for this threat. In the last 30 years of observation by using remote sensing techniques, the shoreline varies by 679 meters. After the year 2000, less accretion and more erosion recorded in this coast. The Indian government take many efforts to mitigate coastal erosion by constructing groins and RMS walls, to protect the villages from erosion. Temporary remedial measures like dumping of stones are adopted at many places. As a part of permanent protection measure so as to create beach and retain them, a series of groin field has to be created in this coast.
