Kovalam Multi-Purpose Reef Update, July 2010

Halfway through monsoon season, Kovalam Multi-Purpose Reef is working to protect Lighthouse Beach in Kovalam, India. The visual results are encouraging and consistent with ASR’s modeled beach salient predictions. 

In the image bellow, a powerful wave breaks on Kovalam Multi-Purpose Reef, dissipating swell energy across the entire length of the reef.

Traditionally, erosion is most severe on the southern end of Lighthouse Beach (lower right hand corner). Kovalam Multi-Purpose Reef is having a substantial effect on sediment retention in this area and we are also seeing accretion in the middle of Lighthouse beach.

Kovalam Multi-Purpose Reef continues to show encouraging results during monsoon season as predicted by ASR’s sediment transport modeling. Demonstrating that Multi-Purpose Reefs provide substantial coastal erosion prevention.

Kovalam Multi-Purpose Reef is an innovative solution for coastal protection and the beach retreat problems experienced in India. Thirty percent of India’s mainland population lives on the coast and relies on the health and security of the coastal environment. In Kerala, some 600 km of coastline is encased by 400 km of rock walls, leading to accelerated beach retreat.

Multi-Purpose Reefs have the following benefits:
-Protect the coast by dissipating wave energy
-Provide marine habitat
-Create a recreational amenity
-Promote socioeconomic prosperity

ASR continues to promote environmentally sensitive coastal protection options that value coastal resources and local interests.
