What are the Differences between gravity dams and earth dams?
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
What are the differences between earthen dams and masonry dams?
Earthen dams have very wide base and suitable to pervious foundation.
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
How are gravity dams constructed?
Gravity dams are constructed using large quantities of concrete to resist the force of water. The concrete is typically poured in layers, allowing each layer to cure before adding the next one. The weight of the dam pushes it down and anchors it to the ground, providing stability against the water pressure.
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 is the importance of dams for a country?
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 .

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 has the author E Sherman Gould written?

Why are dams made?
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.
What are shelters called?
Dams
Where are the gravity dams in India?
India has several notable gravity dams, primarily located in the states of Himachal Pradesh, Uttarakhand, and Maharashtra. Prominent examples include the Bhakra Dam in Himachal Pradesh, the Tehri Dam in Uttarakhand, and the Koyna Dam in Maharashtra. These dams are strategically built to harness river water for irrigation, power generation, and flood control. Additionally, several other gravity dams can be found throughout the country's river systems, contributing to water management and energy production.
What are hydro 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.
