They need to know about gravity so it won't break the pressure. Read a book. IF you don't you are really stupid.
Inadequate design, poor maintenance, earthquake, (terrorism), or other unforseen events. An example of a damanged (not burst) dam is the fairly recent dam in Russia that was severely damaged. The cause I believe is still under investigation.
There are 14 dams in Pakistan. They are:-Akhori Dam-Donhngi Dam-Ghazi Barotha Dam-Gomal Dam-Gomal Zam Dam-Hub Dam-Kalabagh Dam-Karoonjhar Dam-Khanpur Dam-Mangla Dam-Mirani Dam-Shakidor Dam-Simly Dam-Tarbela DamOther names that came up under 'Dams in Pakistan are':-Guddu Barrage-Indus Basin Project-Rawal Lake-Sukkur Barragehttp://wiki.answers.com/What_are_the_names_of_the_various_dams_in_Pakistan#ixzz19cbuQFaG
The state of Alaska has around 167 dams. Some of them are the Akhoik Dam, the Adak Dam, the Akutan Power Dam, and the Blue Lake Dam. Some additional dams on the list are the Lake Demarie Dam, the Engstrom Dam, and the Chester Lake Dam.

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.

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
