Any river dam is necessary for the multiple river projects.

But there are many precautions and parameters that we should maintain during the dam building.

Unnecessary large dams which don't follow the precautions and the parameters can affect our environment badly:

2)the chances of flood also increases along with the increasing height of a dam.
