A barrage is a type of dam or barrier built across a river to control water flow and manage water levels. It can help regulate irrigation, prevent flooding, and generate hydroelectric power. Barrages often have gates that can be opened or closed to adjust the amount of water passing through. In addition to their practical uses, barrages can also create reservoirs, which provide water for drinking and agriculture. They play a crucial role in water management systems, especially in regions where water scarcity is a concern. Examples of notable barrages include the Farakka Barrage in India and the Sardar Sarovar Dam in Gujarat.
