WORLD HISTORY

Detailed explanation-1: -They used arches which provided adequate support for the aqueducts. Arches were constructed by using wooden supports that created the curvature of the arch and were removed after the stone arch was constructed around it (Figure 2).

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: -An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose.

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: -Aqueducts are structures used to carry water from a supply source to distant areas in need of water. The word aqueduct comes from two Latin words, aqua (water) and ducere (to lead). The first aqueducts were built as early as the tenth century BC.
