Hydrology

Hydrology (from Greek: Yδρoλoγια, Yδωρ+Λoγos, Hydrologia, the "study of water") is the study of the movement, distribution, and quality of water throughout the Earth, and thus addresses both the hydrologic cycle and water resources. A practitioner of hydrology is a hydrologist, working within the fields of either earth or environmental science, or civil and environmental engineering.

Domains of hydrology include hydrometeorology, surface hydrology, and hydrogeology, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects.
