What are the relative advantages and disadvantages of the gravity dams over earth dams?
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
What are the materials used in building a gravity dam?
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.
What are the differences between earthen dams and masonry dams?
Earthen dams have very wide base and suitable to pervious foundation.
What are the differences between reservoirs dams and aqueduct?
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
Are masonry dams also called as gravity dams?
no
What are the differences between the mass concrete and reinforced concrete?
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.
What has the author James L Sherard written?

How is gravity useful?
Gravity is a force that keeps things from floating in mid air. Without it you would have been out of the earth by now!! Gravity is a strength deep under the earth (from the inside). Hope this was useful..

What causes the failure of zoned earth filled dams?
Failure of these dams may be caused by, Overtopping Seepage Structural Erosion.
What will happen if many dams are built on the same river?
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.
What is a dam built on?
Natural dams are made of earth, or more rarely wood and silt (e.g. beavers). Manmade dams may consist of packed earth, or stone, or concrete.
