Hydrologists study how water moves across and through the Earth’s crust. They use their expertise to solve problems in the areas of water quality or availability.
Hydrologists need at least a bachelor’s degree for entry-level positions; however, some workers begin their careers with a master’s degree.
Employment of hydrologists is projected to grow 5 percent from 2019 to 2029, faster than the average for all occupations. Demand for the services of hydrologists will stem from increases in human activities such as mining, construction, and hydraulic fracturing.
Hydrologists work in offices and in the field. In offices, hydrologists spend much of their time using computers to analyze data and model their findings. In the field, hydrologists may have to wade into lakes and streams to collect samples or to read and inspect monitoring equipment.
