Hydrology is the general study of the distribution, movement and quality of water on a celestial body, such as our Earth. More specifically Hydrologists study the chemical, biological and physical properties that govern the water cycle - a process by which water continuously circulates between the Earth’s oceans, atmosphere and land.
Hydrology has many applications. Mathematical principles and scientific techniques enable hydrologists to analyse the Earth’s water and make sure it is of a high enough quality, and getting to the people that need it. This can involve gauging water pollutant levels and determining their source, resolving water shortages by implementing storage methods, controlling flooding and managing erosion.
