What are the effects of dam construction?

The construction of a dam converts free flowing rivers into permanently flooded bodies of water. This environmental disturbance affects organisms that are adapted to specific flooding regimes, leading to changes in local ecology. Dams prevent fish species from migrating upstream, disrupting reproduction cycles.

What is construction of dam?

Dam , structure built across a stream, a river, or an estuary to retain water. Many dams are built for more than one purpose; for example, water in a single reservoir can be used for fishing, to generate hydroelectric power, and to support an irrigation system.

How does a dam get built?

Gravity dams are so named because they are held to the ground by gravity – they weigh a lot, and are typically made from concrete or stone. Engineers must de-water the river where the dam is meant to be built . This is done by diverting the river through a tunnel that runs around the intended construction zone.

What city is developed as a direct result of the construction of the dam?

What are dams disadvantages?

Damming of rivers and regulating their flow result in excessive sedimentation at the bottom of the reservoir. This may hamper aquatic life and their migration to other water bodies. Building of dams result in the submergence of land and vegetation. This results in the decomposition of vegetation.

Are dams good or bad?

The potential adverse impacts of dams are well documented, to be sure. These may include altered stream flow, habitat degradation, blockage of the upstream and downstream migrations of fish, mortality of fish passing through turbines, and lower rates of dissolved oxygen downstream of dams .

Why are dams bad?

Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams . This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.

Who built the first dam?

The first constructed dams were gravity dams, which are straight dam made of masonry (stone brick) or concrete that resists the water load by means of weight. .” Around 2950-2750 B.C, the ancient Egyptians built the first known dam to exist.
