a special type of theodolite is needed, often shots are taken from helicopters or low flying planes. a German firm ( Wilde-Zeiss ) made a special theodolite for Dam-Deformation observation and survey work. this was an expensive instrument as it is far easier to make lenses, reflex mirrors, etc to work with straight axes and angles of approach, etc.
how much water can a dam hold back before braking?
The tallest dam in the world is the Nurek Dam in Tajikistan at 980 feet high. In terms of volume of water the Three Gorges Dam in China is the largest.
area is 2, volume is 3
No, but it is the highest arch dam in the US. It was also the biggest dam back in 1935 when it was built. The tallest dam is Rogun in Tajikistan. The largest dam is Three Gorges in China.
Currently operational? The Jari Dam at 84 meters, completed in 1967. the Tarbela Dam is the largest earth filled dam in the world and is second largest by the structural volume. The Mirani Dam is the largest dam in the world in terms of volume for flood protection. There are several damn projects currently under construction or in pre-planning stages so the above will change at some point in the near future.
Hoover Dam contains 3,333,459.2 cubic meters of concrete.
There isn't an exact wight given for the Buffalo Bill Dam in Wyoming. It is a concrete arch-gravity dam and was built with a volume of 82,900 cubic yards (63,400 m3) of concrete. The total volume of dam construction materials is 87,515.00 cu yd (does not include spillway structure).
Surface area and volume calculated separately. Then the ratio is taken
Density is calculated by dividing mass by volume. It is a measure of how much mass is contained in a given volume of a substance.
Kenya's largest dam, the Turkwel, has a height of 153 m, and retains a water volume of 1,641,000,000 m³.
By unit of volume and conversion ,we can say that 1 km =100 dam * * * * * That is true, but a dam is NOT a diameter! A diameter is not a measure of distance.
