Question

Give two advantages of a dam.

Answer 1

Explanation :

1. A dam is a structure that is placed across a stream or river to keep water from flowing downstream.
2. Recreation, flood control, water supply, hydroelectric generation, waste management, river navigation, and wildlife habitat are just a few of the economic, environmental, and social benefits provided by dams.
3. Controlling Floods- Dams not only aid farmers but also help to prevent the loss of life and property due to flooding. Flood control dams collect floodwaters and either release them into the river below the dam under controlled conditions or store or channel the water for other purposes. Dams have been erected for centuries to help control destructive floods.
4. Storage of Water- Dams generate reservoirs that supply water for a variety of purposes, including industrial, municipal, and agricultural.
5. Electricity Production- Dams generate around 103,800 megawatts of renewable electricity, which accounts for 8 to 12 percent of the country's total electrical demand. Because it does not contribute to global warming, air pollution, acid rain, or ozone depletion, hydropower is considered clean.
