Erosion Studies and Rehabilitation of Beach along West Coast of India

The west cost of India from Kannyakumari in Tamilnadu to Thengapattinam bordering Kerala at Thengapattinam is oriented in the east-west direction compared to other two boundaries which are oriented along north-south direction. In these coastal areas the protection measures executed are frequently getting damaged mainly due to unprecedented waves and south west monsoon waves. Hence it was felt to do a detailed study by taking field profiles at selected locations, design of sections and model studies This calls for a proper understanding of the wave hydrodynamics prevailing as it plays a major role in formation of beaches. The stretch is having high tourist potential and it is important to prevent the erosion of beach and stabilize the coast. Field observations were taken and desk studies were made. Based on the studies suitable model studies were carried out and remedial measures were carried out at one site. Post monitoring of the project was done and based on the post monitoring it was inferred that project was a success. The details are explained in the paper.
