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
Some common causes of failure of a gravity dam include inadequate foundation design or construction, overtopping due to excessive inflow or inadequate spillway capacity, seismic events, internal erosion leading to piping or seepage, and poor maintenance or aging of the structure. Regular inspections and proper monitoring can help to identify potential issues and prevent failure.
Yes, dam water is an example of potential energy because it has the potential to do work when released and flows downhill due to gravity. The stored energy in the water is converted into kinetic energy as it moves downstream.
That is potential energy when the water is sitting in the dam. The PE is converted into kinetic energy by running the water down a chute to allow it to gain speed, and then it hits the turbine blades to turn the turbine which drives a generator.
Tarbela Dam is a large dam on the Indus River in Pakistan. It is located in Haripur district of Hazara Division of North-West Frontier Province about 50 km (31 mi) northwest of Islamabad,at height of 485 ft (148 m) above the river bed. Reservoir size of some 95 sq mi (250 km2) makes it the largest earth filled dam in the world. The dam was completed in 1974 and was designed to store water from the Indus River for irrigation and flood control
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.
It is an arch-gravity dam.

masonry dam is usually built by masonry that is basically stones,bricks and cement and in which the force that holds the dam in place against the push from the water is earth's gravity pulling down the mass of the dam

Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
Hoover Dam is what is called an arch-gravity dam. The name curved-gravity dam or arched dam might also be applied. This type of dam uses a curve or arch which has it's apex or "top" directed ''against'' the force of the water it is retaining. This sets up a condition wherein the water will compress the dam against the sides to which it is anchored. Less material fill is required to hold this dam in place compared to a simple gravity dam. Use the link below to learn more. Another link will show lots of images of this and other dams of the same type.

The process for creating a dam depends on the kind of dam, like a wooden or concrete one. For concrete dams, the main materials are concrete and steel reinforcements. The basic and most commonly used shapes to build dams include the buttress dam, the arch dam, the arch-gravity dam, and the multiple-arch dam.
ANSWER A dam is an embankment/a dike made of concrete or earth or other material to form a water reservoir or a hydroelectric reservoir or a defensive barrier against the sea.
