One of the themes of geography class is water and its scarcity and how to share it smartly.

Hydrology is the study of the movement, distribution, and quality of water throughout the Earth, says Wikipedia, including the hydrologic cycle and water resources. A practitioner of hydrology is a hydrologist, working within the fields of either earth or environmental science, physical geography, geology or civil and environmental engineering.

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

Hydrological research can inform environmental engineering, policy and planning.

The term hydrology is from Greek: ὕδωρ, hydōr, "water"; and λόγος, logos, "study".
