Earthen dams have very wide base and suitable to pervious foundation.
A gravity dam is a solid structure, made of concrete or masonry, constructed across a river to create a reservoir on its upstream. The section of the gravity dam is approximately triangular in shape, with its apex at its top and maximum width at bottom. The section is so proportioned that it resists the various forces acting on it by its own weight. Most of the gravity dams are solid, so that no bending stress is introduced at any point and hence, they are sometimes known as solid gravity dams
There are many gravity dams constructed of compacted earth. High dams are generally concrete. All dams require a spillway to be safe. The spillway must be armored.
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
the importance of dams in our country is to stop the flow of water,generate hydroelectricity and does help for the diversion of water. these are of different types such as timber dams ,masonry dams etc . different dams perform different functions and roles .

Dams are typically built to retain water. Some manage or prevent water flow into certain areas (dikes). Dams are also built to be used for hydropower/pumped-storage hydroelectricity to provide energy.
Dams
They are dams that hold back water but also generate hydro electricity by using the force of gravity pushing the water down and through large generators in order to pass through the dam. Hence why theres usually water coming out the other side of them.
Hydro power dams work on the height the water falls inside the dam and generating station (Called Head pressure) This basic pressure created on fluids by gravity
