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 ...
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 first used hydraulic concrete in coastal underwater structures, probably in the harbours around Baiae before the end of the 2nd century BC. [12] The harbour of Caesarea is an example (22-15 BC) of the use of underwater Roman concrete technology on a large scale, [10] for which enormous quantities of pozzolana were imported from ...
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.
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 Battle of the Caudine Forks showed the clumsiness of the Roman phalanx against the Samnites. The Romans had originally employed the phalanx themselves [25] but gradually evolved more flexible tactics. The result was the three-line Roman legion of the middle period of the Roman Republic, the Manipular System. Romans used a phalanx for their ...
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.
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.
