Research and Focussing Exercise (2a) Super dams (b) What happens when we damn the flow of a great river and form an immense body of water where there was none before? (c) Negative effects on building damns (d) Negative impact on the ecosystem‚ people who have to move‚ economy and health (3) Negative effects on the ecosystem -when a big dam is built‚ it may flood several thousand square miles of land -all living things will be drowned (ex. Plants‚ insects‚ etc.) -everything changes (ex.

rise‚ and reducing the capacity of the rivers. It has been estimated that the river bed of the Brahmaputra is rising by 5 cm each year. The building of Farakka dam in India in 1971 is blames for raising the river bed of the river Hooghly‚ a tributary of the Ganges‚ which consequently increases the risk of flooding. The interval between big floods has been shortening-whereas it used to be between 10 and 15 years‚ the 2004 flood came only six years after the last major disaster in 1998.

The project was seen with a lot of economic prowess. One issue of concern that was important was that‚ Bhavnath temple was in middle of the dam reservoir. After a lot of negotiation and assurance to safeguard the interests of the people they agreed. And an increase in the dimension of dam was proposed because of higher promised

world. One such tragedy was the accidental drowning of a young who was vacationing with her family in South Carolina. In both stories‚ a plan to use portable dams to retrieve the body is implemented. These dams fail because of the rapid flow rate at which the water moves. Even though rescuers drill holes in the bedrock to support the dams‚ the force of the water destroys these supports. Divers were sent into the river to see if they could discover exactly where the body was lodged and how to get

downstream of dam and decreased water volume in waterways down/upstream. The decrease in sediments downstream of dams causes nutrients not to transfer so without valuable nutrients plant and animal growth is decreasing. The decrease in water volume in waterways is interfering with the reproductive cycle of plants and animals downstream. For example‚ the Chinook salmon aren’t able to spawn since there were trapped from moving back upstream by dams which formed large pools behind the dams making water

Man-made structures (dams and ancillary structures) will also permanently change the visual setting of the area with the consequential impacts on natural aesthetics. This dam in particular‚ is relatively huge and will in a significant way intrude into the natural setting of the area. As a consequence of the various development components‚ the existing
