In September 2011, the WRD began cleaning the river at a cost of ₹ 10.2 million and the work is expected to be completed within a fortnight. In 2012, the government allotted ₹ 3,000 million towards construction of 337 sewage cleaning systems in

306-420: A brief period. Egrets and cormorants too were cited flocking the river to feast on fish. The river discharged the floodwater at a rate of about 21,500 cubic metres per second (760,000 cu ft/s). A 1928 poem by V. H.

The river is narrow, placid, slow and meandering. The river is primarily fed by discharge from tank and water bodies and has seen a steady drop in freshwater over the years, a primary reason for its present-day condition. However, the core problem of

6936-647: The limits of the Bay of Bengal as follows: Note: Oedjong means " cape " in Dutch language on maps of the Netherlands East Indies (Indonesia). The bay gets its name from the historical Bengal region (modern-day Bangladesh and the Indian states of West Bengal , Tripura and the Barak valley of Southern Assam ). In Ancient Indian scriptures , this water body may have been referred to as Mahodadhi ( Sanskrit : महोदधि, lit.   ' Great water receptacle ' ). Ancient Romans called it Sinus Gangeticus or Gangeticus Sinus whilst Ancient Greeks called it in Ancient Greek : Κόλπος Γαγγητικός , meaning "Gulf of

7038-498: The nature trail which would play a role in erosion management. The nature trail would be based on an "elevated boardwalk" model with "uncompressed natural wood" and "fibre reinforced plastic". The entry and exit would be on College Road near the DPI complex. Apart from the parking facilities on the DPI premises, a stretch along the road between the entry point and the College Road Bridge would be demarcated for additional parking. Five points located at 200-metre (660 ft) intervals along

7140-406: The need for clean waterways. In 2011, the Tamil Nadu Sailing Association planned to build a marina at the mouth of the Cooum river along the southern bank, where yachts and pleasure boats could dock. The ₹ 300-million project involves first building a breakwater in the sea so that the waters at the marina are placid and the boats do not keep bobbing up and down with the incursion of waves. However,

The width of the river course varies all along from 35 to 150 metres (115 to 492 ft), which includes the area occupied by the slums. The major islet in the course of the river is the Island Grounds in Chennai less than a kilometre from the mouth. The river splits into two near Chinthadripet and encircles

7548-517: The pressure of the two plates on each other increase pressure and temperature resulting in the formation of volcanoes such as the volcanoes in Myanmar , and a volcanic arc called the Sunda Arc . The Sumatra-Andaman earthquake and Asian tsunami was a result of the pressure at this zone causing a submarine earthquake which then resulted in a destructive tsunami. A zone 50 m wide extending from

7650-696: The project did not cover Tiruvallur district, which accounts for 54 kilometres (34 mi) of the river stretch. After the DMK took charge again in May 2006, the eco-restoration of the Cooum again came to the fore. To facilitate the implementation of the project, the Chennai River Authority, headed by the Deputy Chief Minister, was formed in December 2009 to clean up the entire stretch of the river within 10 years. This aimed at coordinating

7752-532: The public works department. There is currently the World Bank–funded Irrigated Agriculture Modernisation and Water Bodies Restoration and Management Project to clean up the river, under which the upper reaches of the river are proposed to be covered.

Custom-made tunnel boring machines costing ₹ 600 million each have been imported from Germany for the purpose. Key aspects of

8262-416: The river bank where sewage flows straight into the river. There are 127 identified sewage outfalls into the river, out of which 85 are in use. Nearly 30 per cent of the estimated 55 million litres (15,000,000 US gal) of untreated sewage being let into the waterways of Chennai daily, including by Chennai Metropolitan Water Supply and Sewerage Board, gets into the Cooum river. About 60 per cent of

According to scientists, around 1950, Cooum had 49 species of fish, and by

8466-435: The river every day. Fortunately, there is another 42 km of this river which is still not polluted (as of the year 2015), which can be used to transport the water into Chennai and to store drinking water for Chennai's needs. There is a huge amount of sand deposits in the banks of the unpolluted part of the Cooum river that could rejuvenate the ground water level of numerous villages in the banks of this river. According to

8568-908: The river has been proposed for which a draft ecological plan has been prepared by the Tamil Nadu Urban Infrastructure and Financial Services Limited (TNUIFSL). The project is planned from College Road bridge to Chetpet bridge by the Chennai River Restoration Trust in view of the biological diversity of the area which was undisturbed for decades.

Coral reefs, tsunamis, cyclones, mangrove swamps, battles, and a criss-cross of sea routes in a high trading area combined with piracy have all contributed to shipwrecks in the Bay of Bengal. In chronological order: One of the first trading ventures along the Bay of Bengal was The Company of Merchants of London Trading into the East Indies, more commonly referred to as

9384-502: The trail have been selected for erecting break-out areas including one for a canopy walk. The facility has been planned without electrical fittings and has been designed as a "day trail". It is proposed that Chennai Metro rails are to be built about 30 metres (98 ft) under the bed of the river. The line that comes from the Madras High Court area reaches the metro's Central station in front of Ripon Building , crosses

Polluted part of the Cooum is presently spoiled by filth and pollution, and the water quality has considered to be highly toxic and completely non-potable. The 2004 tsunami cleaned the mouth of the river; however, the river returned to its usual polluted self within
