WORLD HISTORY

Detailed explanation-1: -Aqueducts required a great deal of planning. They were made from a series of pipes, tunnels, canals, and bridges. Gravity and the natural slope of the land allowed aqueducts to channel water from a freshwater source, such as a lake or spring, to a city.

Detailed explanation-2: -aqueduct, (from Latin aqua + ducere, “to lead water”), conduit built to convey water. In a restricted sense, aqueducts are structures used to conduct a water stream across a hollow or valley.

Detailed explanation-3: -Engineers have built aqueducts, or canals, to move water, sometimes many hundreds of miles. Actually, aqueducts aren’t a high-tech modern invention-the ancient Romans had aqueducts to bring water from the mountains above Rome, Italy to the city.

Detailed explanation-4: -Aqueducts moved water through gravity alone, along a slight overall downward gradient within conduits of stone, brick, concrete or lead; the steeper the gradient, the faster the flow.

Detailed explanation-5: -Over a little more than 500 years, 11 aqueducts were constructed to supply ancient Rome with water (Van Deman 1934; Bruun 1991, 97 to 98). The first aqueduct was the Aqua Appia, erected in 312 BC by the censor Appius Claudius Caecus (c. 340 to 273 BC).
