Answer to be written in the exam
1. Regulating and damming of rivers affect their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir , resulting in rockier stream beds and poor habitats for the river's aquatic life.
2. Ironically, the dams were constructed to control floods but they have triggered floods due to sedimentation in the reservoir . For instance: The release of water from dams during heavy rains aggravated the flood situation in Maharashtra and Gujarat in 2006 .

3. Sedimentation also meant that the flood plains were deprived of silt , a natural fertiliser , further adding on to the problem of land degradation .
