Explain the various problems associated with the construction of large dams. Give examples in support of your answer.

Dam is built as the barrier to the flowing of water. It is constructed as the reservoir and it mostly improves the irrigation facility of the area. According to the height, dams can be categorized as large dams and major dams or on the other hand as low dams, medium height dams and high dams.

Various problems associated with the constructed of large dams:

• Wipes out all flora and fauna

When the flow of water is stopped by building dams then mostly the aquatic lives will be affected. The living things in the river will be completely spoilt.

• Increases the chances of flood

When the whole water is stored in one place, then the water will over flow and if the dam's capacity is meagre then there are also chances for cracking and breaking down of dams.

• Chances for interstate disputes

The river flows from state to state and when these rivers are blocked by preventing the entry to another state with dams. Then there are high chances of getting disputes between states. This issue is prevalent in India in case of the states Tamil Nadu and Karnataka for the river Cauvery.

• Chances of triggering an earthquake

There are places which have been experienced the earthquake, flood and other natural calamities because of the construction of dams.
