An example of a rock-fill dam is New Melones Dam in California or the Fierza Dam in Albania. A core that is growing in popularity is asphalt concrete. The majority of such dams are built with rock and/or gravel as the primary fill. Almost 100 dams of this design have now been built worldwide since the first such dam was completed in 1962.
Embankment style diversion dams are constructed to counteract the force of the water pushing on the dam by building a dam with enough weight to withstand the force. Embankment dams are commonly made from materials in the surrounding area where the dam is being built. The materials generally include: sand, gravel, and rocks.
Upstream side of the dam. The dam is a 39 m-tall (128 ft) and 462 m (1,516 ft) long trapezoidal CSG-type with a structural volume of 339,000 m 3 (443,395 cu yd). The cemented, sand and gravel (CSG) design is a mixture of a concrete gravity dam and an embankment dam. Essentially, it is a sand and gravel embankment coated in concrete.
The downstream design refers to the successive raising of the embankment that positions the fill and crest further downstream. A centerlined dam has sequential embankment dams constructed directly on top of another while fill is placed on the downstream side for support and slurry supports the upstream side. [9] [10]
Navajo is a rolled earthfill embankment dam, composed of three "zones" of alternating cobbles, gravel, sand and clay. The dam is 402 feet (123 m) high and 3,648 feet (1,112 m) long, with a width of 2,566 feet (782 m) at the base and 30 feet (9.1 m) at the crest. The dam contains 26,840,863 cubic yards (20,520,000 m 3) of material.
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 Tehri Dam is a multi-purpose rock and earth-fill embankment dam on the Bhagirathi River in New Tehri, Tehri Garhwal district in Uttarakhand, India. [1] With a height of 260.5 m (855 ft), it is the tallest dam in India and the 13th-tallest dam in the world. It is the primary dam of THDC India Ltd. and the Tehri hydroelectric complex. The dam ...
The Saluda Dam [1] or Saluda River Dam, [2] officially the Dreher Shoals Dam, [1] [3] commonly referred to as the Lake Murray Dam, [4] [5] is an earthen embankment dam located approximately 10 miles (15 km) west of Columbia, South Carolina on the Saluda River. Construction on the dam began in 1927 and was completed in 1930.
