It was first known simply as the North River by the British and was believed to be partly responsible for reducing tsunami and cyclone damage to much of the Chennai-southern Andhra coastline

The portion north of the Cooum is known as the North Buckingham Canal, and the portion south of the Cooum as the South Buckingham Canal. 257 km (159.7 mi) of the canal is in Andhra Pradesh, and 163 km (101.3 mi) is in Tamil Nadu.

). The cyclones of 1965/1966 and 1976 damaged the canal, and it is presently little used and no longer well maintained. Within the city of Chennai the canal is badly polluted from sewage and industrial effluents, and the silting up of the canal has left the water stagnant, creating an attractive habitat for malaria-spreading mosquitoes. The North Chennai Thermal Power Station (NCTP) discharges hot water and fly ash into the canal as well. In agricultural areas South of Chennai the former tow path along the scenic areas is still used for light motorcycle and bicycle traffic. On January 1, 2001 the Government of India launched a project to prevent sewage outfalls into the canal and Chennai's other waterways, and to dredge the canal to remove accumulated sediment and improve water flow.

Within the city limits of Chennai much of the canal has been used as the route of the elevated Mass Rapid Transport System (MRTS). MRTS stations such as Kotturpuram, Kasturba Nagar and Indira Nagar have encroached on the canal and narrowed the width of the canal to less than 50 meters in few places.

Buckingham Canal is the most polluted of the three major waterways in the city with nearly 60 per cent of the estimated 55 million litres of untreated sewage being let into it daily, including by Chennai Metropolitan Water Supply and Sewerage Board.

Effect of the Tsunami

Dr. B. Ramalingeswara Rao first identified buffer zone action of Buckingham Canal when he visited coastal areas of 300 kilometres (186.4 mi) along the coast and also he recommended to the Government to renovate the same to mitigate the Tsunami Hazards in future. Further, Ramalingeswara Rao (2005) reported as:
During the 2004 Indian Ocean tsunami, the Buckingham Canal acted as a buffer zone and regulated the Tsunami waves on the coastal region over nearly 310 kilometres (192.6 mi) from Pedda Ganjam to Chennai. The canal all along the coast was filled with Tsunami water, which overflowed at a few places and receded back to sea within 10-15 min. This helped save the lives of several fishermen, especially in coastal Andhra Pradesh

 city and also helped in clearing of the aquaculture debris. The natural growth of vegetation on either side of the canal, has had an effect in Tsunami mitigation; for example in Vakadu Mandal at villages like Pudikappam, Srinivasapuram and Tudipalem, the damages were minimal.
