BANGALORE: A recent scientific research using archeo-astronomy tools has sought to prove that Ramar Sethu is not natural but a man-made sea ridge. It�s a testimony to the civil engineering marvel of an ancient civilisation, that stands even today as a man-made accretion over a natural formation in the sea.

DK Hari, conceptualiser of Bharath Gyan, a NGO which is in to collating specific, scientific knowledge of India has, at a presentation on �Historical Rama� here on Saturday, said the records compiled together talk about Ramar Sethu�s usage until 1480. But it went into disrepair after a debilitating cyclone in 1480, he pointed out.

Hari said Rama indeed was a historical hero and lived nearly 7200 years ago. To rescue Sita from the clutches of Ravana, Lord Rama and his team built the bridge. With the help of Nala as the architect, he designed and executed the project along with the help of �Vanara� tribe. So Rama named the bridge after Nala.

The Sethu came to be known as Adam�s bridge as Sri Lanka�s first Muslim leader, Adham, reached the island from India crossing over this bridge. The Europeans found it easy to call it Adam�s Bridge rather than Nala Setu or Ramar Sethu.

Hari said that the scientific corroborating evidences is the outcome from the analysis of astronomical skycharts using modern scientific tools, geological surveys and research, archaeological research, historical notes of travellers, published Government Gazettes and historical records of the British.

Today, there is a natural sea ridge formation over the seabed linking the land masses of India and Sri Lanka. Hari said “the sea level has risen nine feet above the bridge in the last 7000 years. The bridge is covered under the layers of hardened sands.”

About the execution of the bridge, Hari said that Nala identified a linear chain of islands and converted it with land fills and used it for building the 35-km bridge in just five days at a ratio of 100:10 with an average breadth of 3.5 km as found by NASA and also mentioned in the ancient scriptures.

The dilapidated structure still stands testimony to the engineering marvel of that period. It comprised 103 small patch reefs lying in a linear pattern with reef crest, sand and intermittent deep channels. The space left between the stones allows water to pass through it.

Thus, the knowledge of pore pressure was incorporated in the bridge, Hari said.
