Hydraulics is part of the more general discipline of [[fluid power]]. &lt;br /&gt;
&lt;br /&gt;
The word &amp;quot;hydraulics&amp;quot; originates from the [[Greek language|Greek]] word &amp;#039;&amp;#039;{{Polytonic|ὑδραυλικός}}&amp;#039;&amp;#039; (&amp;#039;&amp;#039;hydraulikos&amp;#039;&amp;#039;) which in turn originates from &amp;#039;&amp;#039;{{Polytonic|ὕδραυλος}}&amp;#039;&amp;#039; meaning [[water organ]] which in turn comes from &amp;#039;&amp;#039;{{Polytonic|ὕδρω}}&amp;#039;&amp;#039; ([[water]]) and &amp;#039;&amp;#039;{{Polytonic|αὐλός}}&amp;#039;&amp;#039; ([[plumbing|pipe]]). The earliest masters of this art were [[Hero of Alexandria]] and [[Ctesibius]]. The ancient engineers focused on sacral and novelty uses of hydraulics, rather than practical applications. Ancient Sinhalese used hydraulics in many applications, in the Ancient kingdoms of [[Anuradhapura]], [[Polonnaruwa]] etc. The discovery of the principle of the valve tower, or valve pit, for regulating the escape of water is credited to Sinhalese ingenuity more than 2,000 years ago. By the first century A.D, several large-scale irrigation works had been completed. Macro- and micro-hydraulics to provide for domestic horticultural and agricultural needs, surface drainage and erosion control, ornamental and recreational water courses and retaining structures and also cooling systems were in place in [[Sigiriya]], [[Sri Lanka]]. Is some stuff that makes things move.&lt;br /&gt;
&lt;br /&gt;
One of the founders of modern hydraulics was [[Benedetto Castelli]], a student of [[Galileo Galilei]].&lt;br /&gt;
&lt;br /&gt;
[[Fluid mechanics]] provides the theoretical foundation for hydraulics, which focuses on the [[engineering]] uses of fluid properties. Hydraulic topics range through most science and engineering disciplines, and cover concepts such as pipe [[flow]], [[dam]] design, [[fluidics|fluid control circuitry]], [[pump]]s, [[water turbine|turbines]], [[hydropower]], [[computational fluid dynamics]], flow measurement, river channel behavior and erosion.&lt;br /&gt;
