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
Fort Randall Dam is a 2.03-mile-long (3 km) earthen dam which spans the Missouri River and impounds Lake Francis Case, the 11th-largest reservoir in the U.S. [2] The dam joins Gregory and Charles Mix counties, South Dakota, a distance of 880 river miles (1,416 km) upstream of St. Louis, Missouri, where the river joins the Mississippi River.
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.
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
The designers of the Manic-5 decided on an above ground power house that was downstream of the dam for safety and cost. The intake was built on the east side of the dam and supplies two 3,400 ft (1,000 m), long 36 ft (11 m) diameter concrete-lined penstocks (tunnels). Just before reaching the power house and its eight turbines, each penstock ...
The dam was built by the U.S. Army Corps of Engineers between 1946 and 1954 for the purposes of flood control, hydroelectricity and downstream navigation. The concrete structure of the dam spans 1,096 feet (334 m) and rises 204 feet (62 m) above the riverbed, housing a power plant with an installed 380 MW capacity. The Dam has prevented over $3 ...

[2] [4] The U.S. Corps of Engineers built earthen dams across two forks of the Kern River to create the Isabella reservoir, Kern County's largest body of water year round with a surface area of 11,200 acres (4,500 ha). During the construction of the dam and reservoir the towns of Lake Isabella and Kernville both had to be moved to higher ground.
