Hydrology is the study of the occurrence, distribution, movement and quality of water, typically focusing upon impacts to human and aquatic
life. A practitioner of hydrology is a hydrologist, often working within the fields of earth science, the biological sciences, physical geography,
or civil and environmental engineering.
