Explanation:

i. Damming of rivers affects the natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir.

ii. Lack of sediment results in rockier stream bed and poorer habitat for the river's aquatic life.

iii. Dams also fragment rivers, making it difficult for aquatic fauna to migrate, especially for spawning.
