[email protected] JULY 2014 Public Works Department EIA Studies for Construction of Groyne at Periyathalai, Tiruchendur Taluk, Thoothukudi District 1.0 INTRODUCTION Groins are considered to be one of the best methods to protect eroding coastline. The coast along the state of Tamil Nadu is very dynamic due to various developmental activities along the coast. This causes sea erosion and hence loss of land to the seas. Periyathalai, with geographical coordinates 8°20′11.043″ N and 77°58′43.134″ E is located in Tiruchendur Taluk of Thoothukudi District in Southern Tamilnadu. This area is a sandy beach prone to littoral drift and sever erosion. The boats are anchored at the sea thus leaving them to the impacts of the open seas. In order to protect the coast and provide a safe landing for the boats, Public Works Department of Government of Tamil Nadu is proposing to construct the Groyne at coastal stretch in Periyathalai. 2.0 DISTRICT PROFILE Geographical Locations of the District and Project site Thoothukudi District lies between latitude 8o 45’ Northern and longitude 78o 11’ Eastern with an area of about 4635 Sq.km.
