hydraulists

A hydraulist is a practitioner who specializes in hydraulics, the study and application of liquids in motion and at rest under pressure. Historically linked to the design and operation of waterworks and hydraulic machinery, modern hydraulists work across civil, mechanical, and environmental engineering to solve problems involving water, wastewater, and other fluids. Their core concern is the control, conveyance, and utilization of liquids in engineered systems.

Typical duties include designing dams, levees, canals, pipelines, pumping stations, and hydropower facilities; shaping municipal water supply networks and wastewater systems; managing stormwater and flood risk; and selecting or developing hydraulic equipment such as pumps and turbines. They model flow with analytical methods and computer tools, assess sediment transport, perform scale-model testing, and ensure safety, efficiency, and compliance with standards. Hydraulists may also work on irrigation systems, drainage projects, and industrial fluid handling.

In contemporary usage, the term hydraulist is less common than hydraulic engineer or hydrologist, but it can appear in historical texts and certain professional contexts to describe practitioners who apply hydraulic science to the design and operation of fluid systems. The field overlaps with fluid mechanics, hydraulics, hydrology, and environmental engineering, and professionals may collaborate with civil engineers, urban planners, and water utilities to implement sustainable, reliable fluid systems.
