Earthen dams have very wide base and suitable to pervious foundation.

Gravity dams:It is made up of masonry or solid concreteIt can be constructed to any heightLess maintenanceEarth dams:It is made up of soil and gravelIt can be constructed to moderate heightIt is cheaper
polders
they are johads ,which are earthen check dams in the alwar district of rajasthan.they are called khadins in jaisalmer ,in rajasthan.
These walls are called dykes or dams. (dijken in Dutch)

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 .

E. Sherman Gould has written: 'The arithmetic of the steam engine' -- subject(s): Steam, Steam-engines 'High masonry dams' -- subject(s): Dams
A reservoir is a body of water kept at a controleld level, usually by a dam. Dams gnerate electricity via the movement of water. Aqueducts are open 'pipes' that exploit gravity to induce water flow
Downstream of the dams the river would get narrow and shallow and upstream of the dams the river would get wide and deep. In between the dams would vary between the two depending on how much water each dam releases and lakes and ponds would probably form between the dams.
The United States is home to many damns of varying sizes and types, One type is the earth fill. The largest of these is the Denison Dam in Denison, Texas.
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.
