Question

The building of big dams gives rise to some problems, list three main problems that may arise. Suggest a solution to any one of these problems?

Answer 1

Hint:A dam is a kind of barrier. It stops or restricts the water flow/underground streams. Reservoirs made by dams not only controls floods but also provide/give water for various types of activities such as
a.Irrigation
b.Human consumption
c.Industrial use
d.Aquaculture
e.Navigability.
Constructing dams can make an effect on the submergence of land and vegetation. This causes the decomposition of vegetation.

Complete answer:Building or constructing of big dams has many major problems connected with it, those are listed below:
1. Construction and maintenance of dams is a very big budget or costly project.
2. It causes major or serious ecological harm. It obstructs the natural and normal functioning of ecosystems and grave destruction to biodiversity.
3. There is an unprecedented injury or damage to the natural habitat of organisms followed by their eradication from their natural habitat.
4. Large dams make sedimentation in the water body leading to warming up of water resulting in the death of aquatic life.
The way out to the problem of sedimentation is the construction of relatively smaller dams with integrated outputs.

Note:Dams assist in preventing floods. They grab extra water so that it doesn't rush wild downstream. Dam operators can let water out by the dam when required. The first upstream flood control dam was constructed or built-in 1948, Cloud Creek Dam in Oklahoma. Damming of rivers and regulating their flow outcome in excessive sedimentation at the bottom of the reservoir. This may cause damage to aquatic life and their migration to other water bodies.
