Hydrology is the science of water. It deals with the origin, distribution, and properties of water on Earth and other planets. Hydrologists work to solve water- related problems. They consider water use from a variety of perspectives- social, economic, legal, scientific, and environmental- to determine how differing viewpoints affect the quality and quantity of a community's water supply. They study pollution carried by water- including oceans, rivers, streams, rain, snow, and ice- and devise methods to clean and control it. Some study weather- related problems such as flood forecasting, drought management, acid rain, and global warming. Others manage water resources so that the goals of all water users are achieved efficiently while protecting the environment.

The knowledge of mathematics, physical science, and chemistry as applied to water-related problems and perspectives, gained from a major in Environmental Hydrology, provides a strong career foundation. Graduates might work as field or lab researchers or consultants studying pollution, weather, or climate; as water resource analysts and managers; or as environmental policy advisers or conservation advocates. This major is also excellent preparation for graduate studies in hydrology, geology, or arid lands resource science. Some of the job titles listed below may require an advanced degree.
