Dams have the primary function of water preservation, while other systems, like floodgates are used to regulate or restrict the flow of water to various regions of the country. The building of massive dams totally changes the interaction between water and soil, disrupting the current equilibrium of the environment, which has taken thousands of years to build in many instances.

Problems are as follows:
> Environmental challenge:- Degradation leading to the depletion of habitats is one of the main problems of dam building. IN the end, this is responsible for disrupting the natural ecosystem’s equilibrium. Even more trees should be planted to cope with this problem.
> Social issue:- Dam building will lead to flooding of neighboring towns and villages. Because of this, a large number would become homeless. Proper compensation should be provided by the government to the injured citizens.
> Economic problem:- Building dams requires an immense sum of capital. It is only after energy production begins that it becomes viable.

Note: The solutions to prevent is, The displaced people from the dam site should be restored by the government to restart their life. There are about 40,000 major dams abstracting the rivers of the planet, completing a revolution in their circulation structure without severe environmental effects.
