Hydrologists study water and the water cycle. They use their expertise to solve problems in the areas of water quality or availability. Hydrologists work in the field and in offices and laboratories.
Hydrologists typically do the following:
Hydrologists use remote sensing equipment to collect data. They or technicians whom they supervise usually install and maintain this equipment. They also use sophisticated computer programs to analyze and model data. They use sophisticated laboratory equipment to analyze chemical samples collected in the field.
Hydrologists work closely with engineers, scientists, and public officials to study and manage the water supply. For example, they work with policy makers to develop water conservation plans and with biologists to monitor marine wildlife. Most hydrologists specialize in a specific water source or a certain aspect of the water cycle, such as the evaporation of water from lakes and streams.
For most jobs, hydrologists need a master’s degree with a focus in the natural sciences. Hydrologists may need a license in some jurisdictions.
A bachelor’s degree is adequate for some entry-level hydrologist positions. Applicants for advanced research and university faculty positions typically need a Ph.D. Few universities offer degrees in hydrology; instead, most universities offer hydrology concentrations in their geosciences, environmental science, or engineering programs.
Students interested in becoming a hydrologist need extensive coursework in math, statistics, and physical, computer, and life sciences. Students who have experience with computer modeling, data analysis, and digital mapping will be the most prepared to enter the job market. Also, hydrologists use geographic information systems (GIS), remote sensing, and global positioning system (GPS) equipment to do their jobs.
Hydrologists work in the field and in offices and laboratories. In the field, hydrologists may have to wade into lakes and streams to collect samples or inspect monitoring equipment. In the office, hydrologists spend most of their time using computers to analyze data and model their findings.
