History World. However, most flows are dominated by viscous effects, so engineers of the 17th and 18th centuries found the inviscid flow solutions unsuitable, and by experimentation they developed empirical equations, thus establishing the science of hydraulics. Another important Hydraulic Engineer in China, Ximen Bao was credited of starting the practice of large scale canal irrigation during the Warring States period (481 BC-221 BC), even today hydraulic engineers remain a respectable position in China. Hydraulics deals with such matters as the flow of liquids in pipes, rivers, and channels Controlling the movement and supply of water for growing food has been used for many thousands of years. Equations developed from the principles of fluid dynamics and fluid mechanics are widely utilized by other engineering disciplines such as mechanical, aeronautical and even traffic engineers. They do so by applying the principles of fluid mechanics in the design and development of water engineering structures, as well as civil and environmental engineering structures and facilities, such as canals, rivers, dams, reservoirs and water treatment plants.

Leonardo da Vinci (1452–1519) performed experiments, investigated and speculated on waves and jets, eddies and streamlining. Before beginning a hydraulic engineering project, one must figure out how much water is involved. They are fed by an ancient irrigation system from the rainforests above the terraces. operated by, moved by, or employing water or other liquids in motion. [7][8][9] It is commonly thought that the terraces were built with minimal equipment, largely by hand. Eupalinos of Megara, was an ancient Greek engineer who built the Tunnel of Eupalinos on Samos in the 6th century BC, an important feat of both civil and hydraulic engineering. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. In 1904 Ludwig Prandtl published a key paper, proposing that the flow fields of low-viscosity fluids be divided into two zones, namely a thin, viscosity-dominated boundary layer near solid surfaces, and an effectively inviscid outer zone away from the boundaries.
