The correct answers are B; Displacement of people living near the proposed dam and C; Lower river water levels in other areas.
Further Explanation:
The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.
When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.
In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.
