The problems associated with the construction of big dams are:
- Excessive sedimentation and salinity in the reservoir.
- Waterlogging: This needs to be done so that the reservoir can be built.
- Soil erosion: A large area might need to be underwater for the reservoir.
- Large scale deforestation: Forrest areas where water was not present would need to be underwater which leads to deforestation.
- Potential flooding situation in case of an earthquake.
