Hydraulic engineering is a specialized skill that involves the design and construction of systems that use fluid mechanics to solve engineering problems. It deals with the study of water in motion, its properties, behavior and interactions with the environment. It is used to design and construct hydraulic infrastructure such as canals, dams, pipelines, and channels to manage water resources for agricultural, industrial, and domestic uses. It also covers the study of water quality, flow measurement, erosion control and flood management. Hydraulic engineering is a critical component in infrastructure sustainability, and its application is vital to economic development, quality of life and public safety.
