Dams play a significant role in providing water for irrigation by diverting the river water into various canals or pipelines, especially in areas where the rainfall is less. It also helps in retaining the excess water flow of the rivers during heavy rains. Dams also play an important role in power generation through hydroelectricity. Dams consume huge forest area during their construction; thus, we can say, their construction decreases the forest cover.
