Engineering hydrology is the science of water resource engineering which deals with the study of occurrence, distribution, movement and the properties of water on the earth or beneath the earth surface or in the atmosphere.

Water resources engineers develop and execute plans for developing water systems that provide clean, safe water in an efficient way that is also good for the planet. They play a central role in civil and commercial construction projects that involve water distribution.
