Dams and barrages play a crucial role in water resource management by regulating river flow, providing water for irrigation, and ensuring a stable supply of drinking water. They also generate hydroelectric power, contributing to energy security and reducing reliance on fossil fuels. Additionally, these structures help in flood control, enhancing safety for communities downstream, and support recreational activities, boosting local economies. Overall, they are vital for sustainable development and environmental conservation in a country.
A barrage is a type of dam that uses gates to control the level of water. They were built to divert water or to dam a lagoon.
The exact number of barrages worldwide is difficult to determine, as new projects are continually being constructed and some may not be officially documented. However, there are thousands of barrages globally, primarily used for irrigation, flood control, and water management. Notable examples include the Farakka Barrage in India, the Sukkur Barrage in Pakistan, and the Sardar Sarovar Dam in India. Each country may have its own distinct number of barrages based on its water management needs.
A tidal barrage is a dam or a weir built across the inlet to a bay or river mouth. There are gates, or sluices, that open to let water in as the tide rises, and out after it falls. This moving water spins turbines to generate electricity.
Only one main dam, Tarbela Dam. Other is for hydro-power generation only, called Ghazi-Barotha Dam. A barrage after Tarbela diverts some of the water towards this Dam and after generation of electricity the water is diverted back to indus. Indus have many barrages. Jinnah barrage, Chashma barrage, Taunsa barrage, Guddu barrage, Shukkur barrage and Kotri barrage. Dam under construction: Diamer-Bhasha Dam Future Dam: Kala Bagh Dam
Dams and barrages play a crucial role in water management and resource conservation in a country. They help in flood control, irrigation, and the generation of hydroelectric power, thereby supporting agriculture and energy needs. Additionally, they can improve water supply for domestic and industrial use, enhance recreational opportunities, and contribute to ecosystem management by regulating river flow. Overall, their multifaceted benefits are essential for sustainable development and economic growth.

The Ganges River has several significant dams and barrages. Notable among them are the Farakka Barrage, which helps regulate river flow and sedimentation, and the Tehri Dam, which is one of the largest in India, primarily for hydroelectric power generation and irrigation. Other dams include the Ramganga Dam and the Karanprayag Dam, while barrages like the Kanpur Barrage also play essential roles in water management. Overall, there are numerous structures along the Ganges, each serving various purposes in flood control, irrigation, and electricity generation.
