 Damodar River is located in the Indian states of Jharkhand and West Bengal. The Damodar River is considered to be one of the most important rivers in eastern India. Mineral resources in the Damodar Valley have made it a large-scale mining and industrial center. The river is also known as the ‘Sorrow of Bengal’ because of its devastating floods in the plains of West Bengal. The river is famous all over the world for the Damodar Valley Corporation (DVC).
Etymology of Damodar River The name of the riverhas been derived from a Sanskrit word; ‘Dama’ means rope and ‘udara’ means belly. Thus, the meaning of the word Damodar is ‘rope around the belly’. Damodar is another name of Lord Krishna. This name was given to Him when his foster mother tied him to a large urn. The river is also known as ‘Damuda’ in a number of local dialects of Jharkhand. The word ‘Damu’ means holy, whereas ‘da’ stands for water. Thus, the meaning of the word Damuda is ‘holy water’. Geology of Damodar River Geology of Damodar River relates to the concentrations of heavy metals and sediments at Damodar River site. It has been found that as the size of the sediments becomes finer, the concentration of heavy metals exhibit a tendency to increase. Course of Damodar River Damodar River has a length of about 592 km (368 mi.). The average rate of discharge of the river is about 10,500 cu ft/s. Chota Nagpur Plateau in Jharkhand is recognized as the origin of Damodar River. Damodar River flows through important cities like Asansol, Bokaro and Durgapur in West Bengal and Jharkhand. Earlier, Damodar River flowed through West Bengal, following a straight west to east route to join the River Hooghly near Kalna. Presently, the river follows an easterly route to journey through Jharkhand and West Bengal to the estuary of the Hooghly River for a length of near about 592 km. In its lower plains, the water of the river is emptied into the Mundeshwari River, which merges with other streams. The maximum volume of the river water enters the Rupnarayan River . The rest of the water flows south of Kolkata into the Hooghly River.  Tributaries of Damodar River
The tributaries and sub-tributaries of Damodar River are Barakar, Konar, Bokaro, Haharo, Jamunia, Ghari, Guaia, Khadia and Bhera. Out of this set of tributaries, the Barakar is considered to be the biggest tributary of Damodar. It has its source near Padma in Hazaribagh district and runs through Jharkhand. The Chota Nagpur Plateau is divided into three parts by the Barakar and the Damodar. The rivers flow through mountainous regions with enormous might, overwhelming anything that comes in their way. The Barakar destroyed two bridges close to Barhi on the Grand Trunk Road in Hazaribagh district and they are the huge rock bridge in 1913 and the succeeding iron bridge in 1946. Floods Caused by Damodar River Previously, Damodar River had been called as the ‘Sorrow of Bengal’. Number of floods has adversely affected the lives of the residents living in the lower Damodar basin in the past. Some of the terrible floods were caused by the Damodar in the following years- 1770, 1855, 1866, 1873-1874, 1875-1876, 1884-1885, 1891-1892, 1897, 1900, 1907, 1913, 1927, 1930, 1935 and 1943. In the years 1770, 1855, 1913 and 1943, most of the Bardhaman town was flooded by the river. In 1789, Maharaja Kirti Chand of Burdwan signed a contract with the British East India Company. Accordingly, the Maharaja had to pay an extra sum for the purpose of building and maintaining river banks to control floods. In the years 1866 and 1873, the Bengal Embankment Act came into being, according to which the authority to construct and preserve the river banks was passed to the administration. Damodar Valley Damodar Valley is spread across Hazaribagh, Ramgarh, Koderma, Giridih, Dhanbad, Bokaro and Chatra districts in Jharkhand and Bardhaman and Hooghly districts in West Bengal. It partially covers Palamu, Ranchi, Lohardaga and Dumka districts in Jharkhand and Howrah, Bankura and Purulia districts in West Bengal. The valley occupies an area of about 24,235 square kilometres (9,357 sq mi). It is considered to be one of the most industrialized parts of India. This valley is rich in deposits of coal. Damodar Valley is considered to be the chief center of coking coal in India. The important coalfields in the Damodar Valley basin are Jharia, Raniganj, West Bokaro, East Bokaro, Ramgarh, South Karanpura and North Karanpura coalfields.  Damodar Valley Project
Damodar Valley Corporation, also known as DVC, is a government organization which came into force on July 7, 1948, by an Act of the Constituent Assembly of India. In this project four multipurpose dams on Damodar River were constructed to form a series of reservoirs - Tilaiya Dam, Maithon Dam, Konar Dam and Panchet Dam. The project provides for flood control, hydro-electricity, coal-fired thermal power plants, irrigation of about 950,000 acres (385,000 hectares) chiefly in West Bengal, afforestation, fish breeding, recreation and the general development of agriculture and industry throughout the valley. It is considered to be the first multipurpose river valley project of independent India. Threats to Damodar River Damodar River banks are known to be rich in mineral resources. Thus, it could be exploited by industrialists. As a result, a number of coal-oriented industries came up in the Damodar basin. Most of them are coal washeries and glass, zinc, cement, thermal power, iron and steel and Government-owned coke oven plants. Thus, contamination of Damodar River commenced due to excessive and defective excavation, outmoded processing activities, oil, fly ash, poisonous metals and coal dust. |
