Question

What are the problems associated with the construction of big dams?

Answer 1

The problems associated with the construction of large dams are:

1. Excessive sedimentation and salinity in the reservoir.
2. Waterlogging: This needs to be done so that the reservoir can be built.
3. Soil erosion: A large area might need to be underwater for the reservoir.
4. Large scale deforestation: Forrest areas where water was not present would need to be underwater which leads to deforestation.
5. Potential flooding situation in case of an earthquake.
