Question

How do hydroelectric dams affect the ecosystem?

Answer 1

Hydroelectric power, also known as hydroelectric power or hydroelectricity, is a source of energy that harnesses the power of moving water to produce electricity, such as water flowing over a waterfall.

Complete answer:
Hydroelectric dams affect the environment in many ways, depending in part on the ecosystem itself and on the dam itself. Generally, the consequences are harmful. Damping a water source significantly alters the flow of that water source. The direction of the river, the depth of the river, the temperature of the river, the width of the river, etc. can be changed. These changes have implications for us. Both large hydroelectric dams and small ones. run-of-the-river plants provide hydroelectric electricity. In several parts of the world, large-scale hydroelectric dams continue to be constructed.
The rivers have been replaced by the lake. Animals in need of certain river conditions may have moved on and may or may not have been successful in the search for other suitable habitats. Plants in the river will also be dramatically affected, so any species that rely on food or shelter for these plants will need to adapt or die out. The migration path would also shift to fish and other marine species, which could, in turn, affect the animals that eat them. Usually, water flows faster in rivers than water flows in lakes. For the species that reside in the neighbouring ecosystems.
As a result, more sediments and nutrients would accumulate in lake water, alter the composition of the water and ultimately make it unsuitable for any species requiring a lower sediment content.
Dammed reservoirs, such as agricultural irrigation, flood control and recreation, are used for a variety of purposes, so that not all dam-related impacts on wildlife can be specifically attributed to hydroelectric power.

Note:
During the construction and dismantling of hydropower plants, global warming emissions are produced, but recent research shows that during the facilities, there can be substantial emissions. These emissions vary greatly depending on the size of the reservoir and the condition of the land flooded by the reservoir.
