    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.

    Work Environment

    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.

    How to Become a Hydrologist

    Hydrologists need at least a bachelor’s degree for entry-level positions; however, some workers begin their careers with a master’s degree. 

    Job Outlook

    Employment of hydrologists is projected to grow 7 percent from 2014 to 2024, about as fast as the average for all occupations. Population growth and environmental concerns are expected to increase demand for hydrologists.
