WORLD HISTORY

Detailed explanation-1: -A canal is a human-made waterway that allows boats and ships to pass from one body of water to another. Canals are also used to transport water for irrigation and other human uses.

Detailed explanation-2: -An aqueduct is a man-made channel that carries water from one place to another. Usually, they are used to supply water to cities and towns. They may also carry water for irrigation, or for hydroelectricity. Pipes, canals, tunnels, and bridges that serve this purpose are all called aqueducts.

Detailed explanation-3: -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-4: -Aqueducts are man-made conduits constructed to carry water. The term aqueduct comes from words meaning “to lead water” in Latin, the language of the Romans who were the first builders of large aqueducts. Aqueducts carry water from natural sources, such as springs, into cities and towns for public use.

Detailed explanation-5: -Aqueduct systems hundreds of miles long have been built to supply growing urban areas and crop-irrigation projects. The water supply of New York City comes from three main aqueduct systems that can deliver about 6.8 billion litres (1.8 billion gallons) of water a day from sources up to 190 km (120 miles) away.
