Water engineering Hydrologists are geophysicists who study the physical properties of the movement and distribution of water. Hydrographic Surveyors examine and analyze the physical conditions, boundaries, flow and related characteristics of oceans, lakes, rivers and other surface waters. Hydraulic Engineers study the science and technology of the static and dynamic behavior of fluids, and design equipment involved, moved or operated by a fluid, especially water, under pressure. Civil Engineers design the machinery, wells and pumps, used to extract water from beneath the earth's surface.
