6-481: The Kurit Dam is a decommissioned arch-gravity dam at the edge of Iran's Dasht-e Kavir . It is located 56 km away from Tabas , Iran , near the eponymous village of Kurit. With a height of 64 metres (210 ft) above its foundation, the Kurit Dam was the tallest dam in the world from its creation in the 14th century until the early twentieth century. The dam was originally 60 m tall but 4 m of height
12-484: 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 water pressure against the canyon rock walls, providing the force to compress the dam. It combines the strengths of two common dam forms and is considered a compromise between the two. They are made of conventional concrete , roller-compacted concrete (RCC), or masonry . Arch-gravity dams are not reinforced except at
18-419: The arch action . An arch-gravity dam incorporates the arch 's curved design which is effective in supporting the water in narrow, rocky locations where the gorge 's sides are of hard rock and the water is forced into a narrow channel. Therefore, the span needed for the dam is also relatively narrow, and the dam's curved design effectively holds the water back while using less construction material compared to
24-512: The spillway . A typical example of the conventional concrete dam is the Hoover Dam . Changuinola Dam is an example of the RCC arch-gravity dam. A gravity dam requires a large volume of internal fill. An arch-gravity dam can be thinner than the pure gravity dam and requires less internal fill. Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and
30-454: The reservoir existed, is now full of silt with the exception of directly behind the upstream face which has been excavated. Kurit Dam belongs to the post-Islamic historical periods and is located in the village of Kurit, Tabas city, Iran ..This dam was constructed of irregular and regular stone material as well as bricks and was employed by the locals for about seven centuries. Arch-gravity dam An arch-gravity dam or arched dam
36-399: Was added in 1850. The dam also contained a water outlet system considered sophisticated for its time. The dam was originally built via limestone masonry with lime, and the addition in 1850 was built via bricks and stone. Currently, the dam does not impound a reservoir , as another dam was built in 2005. and a large segment of its lower downstream face has fallen off. Behind the dam, where
