Hydrologists study how water moves across and through the Earth’s crust.
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.
Hydrologists need at least a bachelor’s degree for entry-level positions; however, some workers begin their careers with a master’s degree.
The median annual wage for hydrologists was $84,040 in May 2020.
Employment of hydrologists is projected to grow 5 percent from 2019 to 2029, faster than the average for all occupations. Population growth and environmental concerns are expected to increase demand for hydrologists.
