Kovalam Multi-Purpose Reef Protects Lighthouse Beach
In February 2010, ASR ltd. completed installation of Kovalam Multi-Purpose Reef to mitigate erosion on lighthouse beach and increase beach sediment levels. In just three months, Kovalam Multi-Purpose Reef is showing very positive results.
Since completion, Kovalam Multi-Purpose Reef added visual amounts of sand to lighthouse beach. Continuing to protect the coast in an environmentally sensitive fashion by dissipating wave energy from incoming swells.

Only a few months after the installation of Kovalam Multi-Purpose Reef a beach salient developed. Similar tidal and wave energy conditions a year later shows dramatic differences in accumulation of sediment behind Kovalam Multi-Purpose Reef and along lighthouse beach. Showing that Kovalam Multi-Purpose Reef is directing sediment towards shore as the design intended.

Kerala has severe coastal erosion problems and is lined with 400 km of seawalls. These seawalls cover roughly two thirds of Kerala’s some 600 km of coastline.
Kovalam Multi-Purpose Reef is showing that alternative and environmentally friendly solutions can provide value to the coast and community while protecting the beach in a sustainable fashion.
A previous image from Lighthouse beach shows current transporting sediment away from the beach and a lack of salient. Kovalam Multi-Purpose Reef is providing a natural barrier that moves sediment towards shore and allowing accumulation of sand.

Recent photos of lighthouse beach from show a very different picture than historical images. The increase in sediment retention is more than apparent. ASR is excited that Kovalam Multi-Purpose Reef is showing such positive results.
The following videos demonstrate the devastating nature of traditional coastal protection devices on Kerala’s coastline and India's need for sustainable and responsible action.

Congratulations for completing installation of Kovalam Multi-Purpose Reef. From the photos I can see the difference is quite impressive at this beach. Great work!
