A hydrologist is a scientist who researches the distribution, circulation and physical properties of underground and surface waters. He or she may help environmental scientists and other scientists preserve and clean up the environment or may search for groundwater. This is one of many green jobs,as well as a STEM career.

Quick Facts

  • Hydrologists earned a median annual salary of $79,550 in 2015.
  • In 2014, there were 7,000 people working in this occupation.
  • The federal government and state governments, and consulting and engineering firms employ hydrologists.
  • The U.S. Bureau of Labor Statistics predicts employment in this occupation to grow about as fast as the average for all occupations through 2024.

How to Become a Hydrologist

You can become a hydrologist with just a bachelor's degree, but if you want to advance beyond an entry-level position, you will have to earn at least a master's degree. Your degree must be in hydrology, or in geoscience, environmental science or engineering with a concentration in hydrology or water sciences. You will need to earn a Ph.D. if you aspire to do advanced research or get a highly coveted position on the faculty of a university.

Some states require hydrologists to have licenses that are issued by state licensing boards. To get one, you will have to meet certain educational and experience stipulations and pass an exam.

Check the licensing requirements of the state in which you plan to work by using the Licensed Occupations Tool on CareerOneStop.

You can apply for voluntary certification from the American Institute of Hydrology. To become certified, you will need a bachelor's degree and five years of work experience, a master's degree and four years of experience, or a doctorate degree and three years of experience.

You will also have to pass a two-part written exam.

How Can You Advance in Your Career?

As an entry-level hydrologist, you will likely begin your career working as a research assistant or technician in a laboratory or office. Alternatively, you may work in field exploration. With experience, you may become a project leader, program manager, or you may be promoted to a senior research position.

What Soft Skills Do You Need?

In addition to the technical skills you will acquire through your education, you will also need certain personal qualities, called soft skills. They are:

  • Critical Thinking: You will use critical thinking skills when developing plans that respond to threats to the water supply.
  • Verbal Communication: Your ability to speak well will allow you to present and clearly explain your findings to others, including those who do not have a scientific background, for example, government officials.
  • Writing Skills: You will have to present your findings to your professional peers, as well as government officials and the public.
  • Analytical Skills: You will have to analyze the data that is collected out in the field and use that information to assess water quality and solve problems.
  • Interpersonal Skills: Hydrologists work in close collaboration with other scientists and public officials.
