Man-made Sources of Water
Canals, Dams, and Wells are all examples of man-made sources of water. These structures are created by humans to collect, store, and distribute water for various purposes such as irrigation, drinking water supply, and industrial use.

Canals
- Canals are artificial waterways constructed to transport water from one place to another.
- They are often used for irrigation, drainage, or navigation purposes.
- Canals can be dug by hand or using machinery, depending on the scale of the project.

Dams
- Dams are barriers built across rivers and streams to hold back water and create reservoirs.
- They are used for flood control, water storage, hydroelectric power generation, and recreation.
- Dams can be made of concrete, earth, rock, or a combination of materials.

Wells
- Wells are man-made structures dug or drilled into the ground to access groundwater.
- They are typically used for drinking water supply, irrigation, or industrial purposes.
- Wells can be shallow or deep, depending on the depth of the water table and the intended use.

All of These
- Canals, Dams, and Wells are all examples of man-made sources of water that play a crucial role in water management and distribution.
- These structures help meet the growing water demands of human populations and support various economic activities.
- By harnessing and controlling water resources, humans can ensure a reliable supply of water for agriculture, industry, and domestic use.
