Reasons for which the multi-purpose projects and large dams have come under great scrutiny and opposition in the recent years are as follows:
1.Multipurpose projects and dams affect the natural flow of rivers and results in poor sediment flow and excessive sedimentation at the bottom of the reservoir and triggered floods.
2. Dams causes fragmentation of rivers and block the migration routes of aquatic fauna , especially for spawning.
3. Artificial reservoirs submerge some parts of the natural vegetation leading to the extinction of Exotic flora and fauna and soil leading to its decomposition over a period of time.
4. Multi Purpose projects and dams induced earthquakes cause water borne diseases and pests and pollution.
