importance of dams in india
Dams and reservoirs play a vital role in India’s infrastructure and development. Here are the key points highlighting their importance and types:
- Water supply: Dams create reservoirs that store water for drinking, agriculture and industry, ensuring a reliable supply even during dry seasons.
- Irrigation: They provide essential irrigation to vast farmland, making a significant contribution to food security and rural livelihoods.
- Hydropower: Many dams are equipped with hydroelectric plants, generating renewable energy and reducing dependence on fossil fuels.
- Flood control: Dams help regulate river flows, reducing the risk of flooding in downstream areas during heavy rains.
- Recreation: Reservoirs often become recreational sites for activities such as fishing, boating, and tourism, promoting local economic development.
- Ecosystem support: Well-managed reservoirs can support local ecosystems by maintaining water levels and quality.
- Navigation: Dams can improve navigation on rivers by stabilizing water levels and facilitating transportation and trade.
Type of dam
- Gravity dams: These dams rely on their weight to resist the force of water. They are usually made of concrete or masonry (e.g. Bakla Dam).
- Arch Dams: These dams curve upstream and transmit water pressure to the canyon walls. They are very effective in high pressure environments such as the Idukki Dam.
- Embankments: These dams are constructed of earth materials with broad foundations and are usually used in areas with loose soil (e.g. Hirakud Dam).
- Rockfill Dams: These dams are made of compacted rock material and provide stability and drainage capabilities (e.g., Tehri Dam).
- Masonry Dams: These dams are constructed of stone or bricks and are designed to withstand huge water pressures (e.g. Nagarjuna Sagar Dam).
- Concrete faced rockfill dams: These dams combine rockfill material with a concrete face to prevent leakage and increase strength (e.g. Sardar Sarovar Dam).
- Barrage: A low-head diversion structure that controls the flow of a river without creating significant water storage (e.g., Farakka Barrage).
in conclusion
Dams such as Bhakra Nangal and Sardar Sarovar have played an important role in hydroelectric power generation, greatly meeting the country’s energy needs while promoting sustainable development.
However, the geopolitical landscape surrounding water resources is increasingly complex. China’s proposal to build large-scale hydropower projects on the Brahmaputra River has caused serious concern in India.
The “mega dam”, with an estimated capacity of 60 gigawatts, could alter water flow patterns, impact agriculture and increase flood risks in downstream areas such as Assam.
The strategic implications of the project are likely to heighten tensions between the two countries, especially given China’s historical reluctance to share hydrological data.
However, India has numerous dams across states, each playing a key role in water management and economic growth.
Among them, Maharashtra has the largest number of dams, with a total of more than 2,300 dams as of 2018.
In comparison, Madhya Pradesh ranks second, with about 900 dams, mainly used to support irrigation and drinking water supplies, but also to produce hydroelectric power.
Gujarat ranks third with about 630 dams, which were originally built as flood control measures and later expanded for purposes such as providing drinking water and irrigation services.
Chhattisgarh, meanwhile, has about 250 dams, but the number is less compared to other states.
Finally, Karnataka joins the top five with around 230 dams, making extensive use of them for tasks ranging from water storage and supply to preventing floods and harnessing hydropower potential.
