which is the oldest manmade dam in the world, and what the contraversory arise on it?

Answer 1

The oldest dam was NOT built in the 1930's. The first dams were believed to have been built in ancient Mesopotamia around 5000 BC, but the earliest recorded dam was probably one on the Nile River at Kosheish, Egypt, built around 2700 BC to provide water for Memphis, the ancient capitol of Egypt. It was flooded and destroyed shortly after construction because no spillway was built.

The oldest dam still in use was built in 1300 BC at Orontes, in Syria.

Answer 2

Oldest Dam In The World

Answer 3

The history of dams has been traced to about 2900 BC when a 49-ft (about 15m) high masonry structure was built on the Nile at Kosheish to supply water to King Menes' capital at Memphis. Evidence exists of a masonry-faced earthen dam built about 2700 BC at Sadd-el-Kafara, about 19 miles (about 30.5 km) south of Cairo. This dam failed shortly after completion when it was overtopped by a flood in the absence of a spillway. The oldest dam still in use is a rock-fill structure about 20 ft (6.1m) high on the Orontes in Syria, built about 1300 BC.

That would make it about 3300 years old.

The controversy over the first two is fairly simple (aside from the fact that there's some scholarly argument whether the first one at Khosheish existed). Basically ... why dam up the river in the first place? Both of these locations are quite a way inland - so either the local ruler was looking to save water for his own purposes, or he was trying to impose restrictions on those downstream. Not good politics, in a land where water is a precious commodity ...

Answer 4

Ok so wiki was wrong

The dam on the Orontes River in Syria is still in use.


I believe Kallanai dam or Grand Anicut, on the Kaveri River in Southern India is the oldest dam still in use.

Claimed to have been built before 200AD

I couldn't find any controversy regarding it

Answer 5

At least.I suspect the true figure is over six and a half billion, but I'm not sure if other animals have religious beliefs. I suggest if you are looking for the 'right' one you first of all get your head around the concept that religion is a way of trying to formalise subjective human experience. It is possible that the "right" one for you might not be the right one for other sentient beings.

Answer 6

Norris Dam is a Tennessee Valley Authority hydroelectric and flood control structure located on the Clinch River in East Tennessee. It was the first dam constructed by TVA, in the mid-1930s. However, it is not the oldest dam owned and operated by TVA, which subsequently purchased the assets of the former Tennessee Electric Power Company, including some dams which were built earlier.

Hungarian-American architect Roland **** revised the initial plans from Bureau of Reclamation engineers, and gave the poured-concrete Norris Dam a modernist style that was controversial, advanced for this time and place, and landed **** the job of Chief Architect for the TVA from 1933 through 1944.

Construction began in October, 1933. The dam was completed in March, 1936, constructed at a cost of $36 million. Approximately 2900 families were relocated from reservoir lands during the construction. The dam is named in honor of Nebraska Senator George Norris, who was a longtime supporter of governmentally-owned power in general and TVA in particular. The town of Norris, Tennessee was a planned community initially used to house the workers involved in the construction of this dam.

Norris Dam is a straight concrete gravity-type dam. The dam is 1860 feet (570 m) long and 265 feet (81 m) high. Norris Lake is the largest reservoir on a tributary of the Tennessee River, with 33,840 acres (137 km²) of water surface and 809 miles (1302 km) of shoreline. The dam is equipped with two 50 MW electrical generators.

The reservoir is often relatively clear, especially for one of this age, due to the rocky nature of the beds of most of the tributary streams, and is considered a prime destination for fishermen. Due to the height of the dam and the relative depth and steepness of the valleys of the some of the streams impounded, parts of this lake, especially the downstream portions near the dam, are very deep for a man-made impoundment of this kind.
