Remains of the Band-e Kaisar dam, built by the Romans in the 3rd century AD. In Iran, bridge dams such as the Band-e Kaisar were used to provide hydropower through water wheels, which often powered water-raising mechanisms. One of the first was the Roman-built dam bridge in Dezful, [24] which could raise water 50 cubits (c. 23 m
The Aswan Dam, or Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. When it was completed, it was the tallest earthen dam in the world, surpassing the Chatuge Dam in the United States. [ 2 ]
The completed Gordon Dam was the only dam built on the Gordon River, despite the support of Tasmanian politicians such as Eric Reece, Robin Gray, and others to build the Franklin Dam further downstream. The construction of Gordon Dam resulted in some flooding of the connected Lake Pedder as planned.
For dam construction, two cofferdams are usually built, one upstream and one downstream of the proposed dam, after an alternative diversion tunnel or channel has been provided for the river flow to bypass the foundation area of the dam. These cofferdams are typically a conventional embankment dam of both earth- and rock-fill, but concrete or ...
The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over two miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. [4]
Detention dams have two basic designs. [5] The detention dam can be made from concrete or masonry, usually with a metal reinforcing substructure. The concrete or masonry style dam commonly has a cross sectional shape similar to a right triangle with the sloping face pointing downstream and the perpendicular face pointing upstream.
Arch-gravity Hoover Dam architectural plans. An arch-gravity dam, or arched dam, is a dam with the characteristics of both an arch dam and a gravity dam.It is a dam that curves upstream in a narrowing curve that directs most of the force from the water against the canyon rock walls, which provide the force to compress the dam.
