5. Question
Why is sedimentation harmful for reservoirs?
1. It results in rockier stream beds.
2. A lot of sedimentation may cause local flooding.
3. It adversely affects the reservoir bed habitats for the aquatic life.
Select the correct answer using the codes below.
CorrectSolution: D
Justification:
Statement 1 and 2: All rivers contain sediments. When a river is stilled behind a dam, the sediments it contains sink to the bottom of the reservoir. As the sediments accumulate in the reservoir, so the dam gradually loses its ability to store water for the purposes for which it was built. If sedimentation continues, it increases water level and can even cause floods.IncorrectSolution: D
