What is gravity dam?
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
Hydroelectric dams use the kinetic energy of water to produce electrical energy What is the environmental drawback of building hydroelectric dams?
Dams disrupt a river's ecosystem.
How are magnifying lenses constructed?
Have you ever wondered how a magnifying glass is constructed? A magnifying glass is constructed by using a convex lens to curve and magnify objects. A magnifying glass is also constructed out of glass.
What is the line called between gravity and no gravity?
Sorry; there is no line between gravity and no gravity. Gravity is everywhere.
Why is gravity called gravity and not anything else?
Because, the person who discovered gravity was named Gravity Dickakiss
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 gravity dams and earth dams?

Are masonry dams also called as gravity dams?
no
What are constructed to control the flow of river water?

How many check dams are constructed on the river godavari?
4
What are the purpose of PA DAMS?
The purpose of the dams that are found in the state of PA are to prevent water from entering another water source or landform. Dams are often manmade, but can be constructed by animals like beavers.
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.
Why dams are constructed in a safer place?
The construction of the Glen Canyon Dam formed which body of water?A. Lake Mead B. Grand River C. Canyon Lake D. Lake Powell dams are constructed in a safer place because of the following reasons:*it must not be build in earthquake occurring place.*while moving vehicles,the dam should not fall.*the dams should build very strong.*it is useful for irrigation.
How come a bridge or a dam can be built in water when water is the worst enemy of civil structures?
Bridges and dams are built after a coffer dam is constructed to reroute the water. When the structure is complete the coffer dams are removed or destroyed.
Why have humans created dams and levees?
Man Made dams are constructed for several reasons. One may construct a dam to balance water height or achieve agricultural irrigation.
Which are the dams constructed under DVCS?
Four multipurpose dam were constructed during 1948 to 1959- 1- Maithon Dam 2- Panchat Dam 3- Tilaiya Dam 4- Kunar Dam
