The Chola Dynasty port city in Tamil Nadu that vanished from maritime historical past round 1,000 years ago will probably be digitally reconstructed by a consortium led by the Department of Science and Technology, officers instructed .
DST officers mentioned there are exhaustive narrations in works of Sangam Tamil literature to infer that the city, situated 30 km from the present Poompuhar city in southern TN, was submerged due to “kadalkol” or rising sea ranges.
“However, despite several studies on Tamil literature, archaeology, history, epigraphy, underwater exploration and geosciences, the mystery of the exact location of initial establishment of Poompuhar, its age, later shifts, along with periods, time-series spatial evolution in the present location at the mouth of river Cauvery, and the reasons and periods of its extinction, remain unresolved,” a DST official mentioned.
“The study involves underwater surveys and photography by remotely operated vehicles and sea bed drilling, remote sensing-based geodynamic studies to bring out comprehensive information on the time series evolution and extinction. It also involves the visualisation of geodynamic processes of the last 20,000 years like land subsidence, sea-level rise, Cauvery’s migration, floods, tsunami, cyclones and erosion. The information extracted from the studies will help digitally reconstruct the life history of Poompuhar,” the official mentioned.
Dr Ok R Murali Mohan, head of the ICPS division at DST, mentioned the same challenge is being rolled out on the Dwarka city in Gujarat, too. “A lot of good work has already been done to map Dwarka but not much in Poompuhar. If we look at both these sites, they are diagonally opposite in direction. What are the geo-dynamics that happen in the Bay of Bengal? Did similar things happen on the other side also, geologically these two sites might be connected, we don’t know,” he mentioned.
The reconstruction of Poompuhar is a part of DST’s Indian Digital Heritage challenge — an exhibition of its first challenge ‘Digital Hampi’ is at the moment on show on the National Museum right here.
“DST looked into heritage documentation and works with technologies that can be applied to digitally convert our monuments into virtual spaces,” Mohan mentioned.
The Hampi challenge brings to life tangible and intangible heritage within the space providing guests a peak into how marketplaces regarded and the musical pillars had been constructed.
“In our second phase, we are looking at heritage that is currently underwater in Gujarat and Tamil Nadu. The focus is now to find evidence on how these were built, whether photographs of the structures are available and the reasons that contributed to the submergence of the city,” Mohan mentioned.
For the Poompuhar challenge, the DST has arrange a community of 13 academicians and analysis establishments to hint the historical past of the traditional city. Some of those embrace the School of Marine Sciences, Alagappa University, Academy of Marine Education and Training University in Chennai, National Institute of Ocean Technology and others.
Professor S M Ramasamy from Bharathidasan University, who’s the nationwide coordinator ‘Project Digital Poompuhar’, mentioned the port city flourished in inter-continental commerce however vanished. “Our first step is to study when and where it was established, where it shifted to and its present location. What were the phases and periods through which it shifted,” he mentioned.
Researchers say that preliminary research carried out by the Indian Remote Sensing Satellites present that the city was established initially within the Cauvery Delta-A about 30km away from the current city round 15,000 years ago.
“It shifted further 10 km to the west to Delta-B around 11,000 years ago and again further 10 km west to Delta-C around 8000 years ago. Finally, it was re-established at the present location at the mouth of the river Cauvery around 3,000 years ago. The shifts took place due to the continuous rise of sea levels and the submergence of the deltas,” mentioned an official.
Further research found a harbour-like construction in addition to sea partitions and possibly a bridge. “These have given new insights about the life history of Poompuhar and the social, cultural, and technological evolution of this part of the country as well as the age of Poompuhar from 3000 years to 15,000 to 20,000 years. The study is also expected to provide packages of scientific information not only on the life history of Poompuhar and the socio-cultural evolution but also the science and technological evolution and the disaster history of this region,” the official mentioned.
