The Flow of Water

Abstract

THE control of water is one of the oldest branches of civil engineering, and to-day problems connected with the flow of fluids are of first importance in connexion with many scientific and technical activities. Like the engineers of ancient times, the modern engineer has to control the flow of water in canals and aqueducts; where they constructed small reservoirs, he constructs tO-day reservoirs of very great capacity. The ancients drew water from shallow wells by primitive means; the engineer to-day uses deep well power- driven pumps to draw water from strata hundreds of feet below the surface of the earth. For thousands of years the power of flowing streams has been utilised to work simple machines, but to-day the rains that fall on the mountain areas are directed into channels that convey the water to machines developing tens of thousands of horse-power.
