Disadvantages of Dams
Constructing dams has some severe negative consequences on the environment.
- Dam construction requires large areas of land because of which farmers and social life associated with the land will be disturbed.
- Besides social life, the greenery in the construction area will be disturbed which has a great impact on the environment.
- Dams are huge structures and their construction would need digging out deep layers of earth disturbing the topography.
- They can also cause disturbance in the migratory patterns of birds and fishes by disturbing their natural habitats.
- Above all, constructing dams would need a large amount of public money.
- Debris and sediment buildup in the reservoir can reduce the water-holding capacity.
- Dam failure is the biggest hazard. Design failure or unexpected forces causing dam failure can lead to severe damage to the human population and living species thriving in the dam locality.

Overview on Dams
The advantage of dams lies in their ability to regulate water flow, prevent floods, and store water, thus ensuring a stable water supply for human needs and economic activities. The dams are large barrier-like constructions built on flowing water systems like rivers and streams. The main benefit of dam construction is water storage. When the water level upstream exceeds the dam capacity, floodgates will be opened slightly. This will help in a controlled flow. In this article, we will read about dams, the advantages of dams, their importance for human benefits, and their disadvantages.
