Firstly, they would have to flood the area in order to create the dam, as a result people will have to evacuate the area and move to other places.

Dam can be for Hydro Electric Power (HEP) . Hep produce energy by harnessing water motion . Water Flows through a pipe then pushes against and the turn blades in turbine that spin to power the generator to produce electricity

# data[].attributes.body
Firstly, dams can produce hydroelecrtic power which is a renewable energy source.

Secondly, dams can reduce the risk of flooding which can save the areas prone to flooding.

Thirdly, dams can be used to store water which can be used for multiple reasons.

# data[].attributes.body
Firstly, dams can produce hydroelectric power which can be used as a source of energy which is renewable

Secondly, dams will minimize the risk of flooding in nearby surrounding areas if there is high precipitation

Thirdly, dams can be used as a reserve for water which can then be used for Agriculture, Industry or for Domestic purposes

# data[].attributes.body
In my opinion,There are a lots of positive impact

1)We can produce more energy to meet the demands of such as economy and Domestic,

2)The cost is less so thus, government can save more money

3)Benefit of Economic. such as tourism (want to visit), More energy produced(more energy can serve for manufacturing, Education, Financial etc)

Dams may provide numerous benefits towards civilians. One example is the fact that dams can hold water in a reservoir so that it can be used for irrigation, more specifically, during the arid seasons.

# data[].attributes.body
Firstly, multi purpose dam give people nearby to do agriculture, as a result subsistence farming can be done

Secondly, dam can create new ecosystem behind the dam or reservoir. As a result biodiversity is maintain

Thirdly, dam reduce rick for flooding to happen, As a result, people can live in the area

Leaching of minerals and nutrients from soil which results into the soil becoming infertile because of the dam not being efficient due to siltation, and therefore, agriculture cannot be done and plants would not be able to grow efficiently.

# data[].attributes.body
It disturbes the food chain because as the dam is built and machinery is used, the construction makes the water dirty and muddy as a result it kills the small fishes.

Multipurpose dam project comes with its disadvantages too.

As time pass, water flow and erode its walls. This eroded materials is made of fine silt that will build up throughout the river’s channel causing it to be silted.

In another case, the wall becomes so heavily eroded resulting it to collapse and flood the nearby area.

However, the disadvantages of dams are firstly, it causes displacement of people living in an area since the development of dams requires a lot of land area since it has to be deep and spacious.

# data[].attributes.body
Firstly, the Dam is affecting farmers crops. When the dam gets are open and closed the land receives a variable amount of water from the Dam which can cause flood or drought.

# data[].attributes.body
Dams are expensive to maintain and build which will increase the expenses of the country.

# data[].attributes.body
firstly, to maintain the dam is expensive bcs they need to remove the siltation that build up behind the dam by using machineries.

# data[].attributes.body
Firstly, people will be displaced and relocated because the dam needs bigger space to build, therefore, people will be left homeless.

# data[].attributes.body
Firstly, to build a dam, it is a requirement to flood the area in order to store the amount of water needed to generate electricity. As a result, if it is built near developed areas like the Three Gorges Dam, they are required to move thousands of people, which costs a lot of money as it takes effort in transporting and providing distribution of food to the people as they migrate to other location. Furthermore, the government are required to pay the people for their resettlement.

# data[].attributes.body
Firstly, it can destroy historical artefacts as the process needed to build the dam requires to clear up the area/route for the dam construction.

# data[].attributes.body
the dam structure are under a lot of pressure, which can eventually deteriorate and fail as a result there would be a major flood

# data[].attributes.body
There is a risk of flooding if the dam breaks due to disasters such as earthquakes which can weaken the walls of the dam, leading it to fracturing and eventually flood the downstream. Furthermore, since the aquifers hold a large amount of water, there is a high chance of an overflowing of water inside the aquifer of the dam if the flow is blocked from siltation, especially if there are higher precipitation from rainfall.
