An analysis was done as part of the Shoreline Management Plan (SMP), mandated by the Coastal Regulation Zone (CRZ) Notification, 2011.
The Shoreline analysis, conducted by the National Centre for Coastal Research (NCCR), has identified 69 erosional stretches along the Tamil Nadu coast, and flagged 20 sites that require reformation.
Nearly 13.5% of Tamil Nadu’s coastline is occupied by artificial structures.
Kanniyakumari and Tiruvallur stand out for having the highest concentration of coastal structures.
