The Romans built dams to store water for irrigation. They understood that spillways were necessary to prevent the erosion of earth-packed banks. In Egypt, the Romans adopted the water technology known as wadi irrigation from the Nabataeans. Wadis were a technique developed to capture large amounts of water produced during the seasonal floods ...
In order to separate the gold and silver, however, the Romans would granulate the alloy by pouring the liquid, molten metal into cold water, and then smelt the granules with salt, separating the gold from the chemically altered silver chloride (Tylecote 1962). They used a similar method to extract silver from lead.
The Romans were the first to exploit mineral deposits using advanced technology, especially the use of aqueducts to bring water from great distances to help operations at the pithead. Their technology is most visible at sites in Britain such as Dolaucothi where they exploited gold deposits with at least five long aqueducts tapping adjacent ...
The Romans used hushing, a method of hydraulic mining that uses water to erode the rock. [1] This would be accomplished by using holes to funnel water into the area, thus breaking it up. The water was supplied to the area through aqueducts , [ 2 ] and it would then be stored in a tank, which would flood the area when opened.
Calcium is a binding agent in Roman concrete, which makes it remarkably strong. Figuring out where it came from was the key to solving this architectural mystery.
Romans used a phalanx for their third military line, the triarii. These were veteran reserve troops armed with the hastae or spear. [26] Rome conquered most of the Hellenistic successor states, along with the various Greek city-states and leagues. As these states ceased to exist, so did the armies which used the traditional phalanx ...
The most prevalent hydraulic pump used in maritime situations in ancient Rome was the bilge pump, which functioned to siphon collected water out of a ship's hull (Oleson 1984). The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps.
The Romans recycled public bath waste water by using it as part of the flow that flushed the latrines. Terra cotta piping was used in the plumbing that carried waste water from homes. The Romans were the first to seal pipes in concrete to resist the high water pressures developed in siphons and elsewhere.
