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 detention dam design must take into account the probability of overtopping occurring and be designed accordingly. Detention dams built to restrict flow rate regulate the amount water released into channels. [2] Detentions dams used to replenishment the subsurface water or groundwater hold surface runoff to allow the ground to absorb the ...
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section.
The next one downstream, Chief Joseph Dam, which was built decades later, also does not have fish passage. This means no salmon reach the Grand Coulee Dam or the Colville Indian Reservation . The third large dam downstream, Wells Dam , has an intricate system of fish ladders to accommodate yearly salmon spawning and migration.
Hoover Dam from the air. Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and the arch action. [3]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.
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 dam was originally built by King Karikalan of the Chola Dynasty in c. 100 – c. 150 CE. It is located on the river in Thanjavur district, exactly 14 km from the city of Tiruchirappalli and 45 km from the city of Thanjavur. The idea behind the construction of the dam was to divert the river to the delta districts thereby boosting irrigation.
