Earth is unquestionably a blue planet. In addition to the water found in oceans, rivers and lakes, our planet’s water resources are comprised of water vapor, glaciers, soil moisture, underground water reserves and living creatures. Clearly, water is significant both for the planet and for all life that exists on it.
Hydrology is the study of water and its properties, distribution and movement, as well as the relationship of water resources with the rest of the environment. So, what is a hydrologist? Hydrologists research these water-related issues and manage societies’ water resources.
If you have a passion for environmental science and the process of conducting research, you might consider becoming a hydrologist. Start by taking a deep dive into the hydrology job description that follows, and then explore environmental science degree options.

It’s the job of a hydrologist to determine how to best manage water resources and examine how human activities impact them. Hydrologists are primarily problem solvers. They may work on a wide range of issues, such as the following:
Water is among the most important resources on our planet. Without it, life would not exist. Hydrologists are stewards of this crucial natural resource.
Hydrologists split their time between the office and the field. While in the field collecting samples and working with monitoring equipment, hydrologists may need to access hard-to-reach areas and rugged terrain. In the office, hydrologists spend a great deal of time analyzing the data they have collected.
The largest employer of hydrologists is the federal government. Other hydrologists work for state or local governments. Still others work for engineering firms and similar organizations, and there are some opportunities for hydrology professionals in institutes of higher education, where they may teach and conduct research.
Lastly, qualified scientists do have opportunities to give back to communities. They may do this by working for nonprofit organizations focused on environmental justice issues or by volunteering for these organizations.
For example, consider the story of Wendy Robertson, a hydrogeologist and professor at Central Michigan University. After teaching two semesters during the school year, Robertson travels each summer to Sub-Saharan Africa to build sustainable water projects for villagers who would otherwise not have easy access to clean water.1 This is just one way in which scientists who specialize in hydrology can help make the world a better place.
There are entry-level positions in this field available to graduates who possess an undergraduate environmental science degree. However, many hydrologists earn a master’s degree before beginning work in the field.
It’s ideal to choose a master’s degree program that is specific to hydrology. Alternatively, students might look for a program in geosciences or environmental science with a concentration in hydrology.
With a master’s degree, graduates are well-qualified to pursue positions as hydrology scientists. After gaining at least a few years of relevant work experience, professionals may decide to go back to school to earn their doctoral degree. This terminal degree is typically a requirement for individuals who intend on making the transition to a faculty or advanced research position at a university.
Yes, the demand is primarily due to the environmental changes caused by global climate change, which is threatening water resources and increasing the risk of both droughts and floods. Hydrologists are needed to develop evidence-based water management programs in an effort to alleviate the effects of climate change.
Another factor fueling the demand for hydrologists is population growth. As the population climbs, so too does human activity. This contributes to a greater need for resources gleaned through hydraulic fracturing, construction and mining. In turn, all of these activities negatively affect the natural water cycle and clean water availability.
Additionally, population growth contributes to human expansion to locations previously uninhabited by humans. This can create water scarcity and increase the risk of damaging floods. All of these factors combined are contributing to the rising demand for skilled hydrologists and smart water management programs.

The hydrologic cycle, also known as the water cycle, occurs continuously all over the planet. It starts when water evaporates and moves as water vapor into the atmosphere. Then, the water falls back to the planet’s surface to the oceans and land masses.
Once back on Earth, the water may be frozen into icebergs or captured by oceans and rivers. It may soak into the soil, where it can make its way to groundwater reserves or be sucked up by the roots of plants. Human activities—ranging from the operation of a manufacturing plant to the irrigation of a home garden—affect the hydrologic cycle, as well as the availability and quality of water resources.
For example, consider a manufacturing plant that uses water to cool its machinery and prevent overheating. Once the water is used, it may be discharged to a nearby river or lake. The quality of the discharged water will be affected, even if it’s treated first.
A hydrologist is a scientist who studies water and its movement across and through the Earth’s crust. Hydrologists study how water and various forms of precipitation like snow and rain affect surrounding environments to understand how environmental factors affect the quantity and quality of available water on Earth. One crucial concept in hydrology is the hydrologic cycle.
Now that you know the answer to the question, “What is a hydrologist?” you might consider entering this field. The planet’s water is essential for all life; if you’ve decided that you would like to dedicate your career to protecting this valuable resource, you can get started right now. If you’re still in high school, it’s time to visit your guidance counselor to discuss your course load.
Sign up for as many earth science, chemistry, biology and physics classes as possible. Computer science and communications classes are also important for aspiring hydrologists. In addition, look for relevant extracurricular activities, such as a science or public speaking club.
If you have the opportunity to participate in a science fair, consider conducting a water-related project. Students who live near universities or colleges can look for school-affiliated summer field experiences or camps.
Internship experiences in any science field will also be helpful for aspiring scientists. You can look for nearby internships on the job board of the American Water Resources Association website.
When it’s time to apply to colleges, look for a rigorous environmental science program. A bachelor’s degree will be sufficient to get your foot in the door in this field. However, you should plan on earning a master’s degree as well, and you may later complete a doctoral degree to further enhance your career opportunities.
Depending on the requirements of the state in which you plan to work, you may need to earn a license. You’ll have to check with your state’s licensing board to determine the eligibility requirements. Typically, hydrologists who need to obtain a license must demonstrate specific academic credentials and work experience, and they usually must pass a licensing exam.
It is not mandatory for hydrologists to be certified, although some employers may prefer it. Earning a voluntary certification can open the doors to higher level opportunities for hydrologists.
The American Institute of Hydrology (AIH) is the certifying body in the U.S. To obtain a certification as a hydrologist, you will need to pass a two-part exam. You must also meet one of the following eligibility criteria:
Your formal education and on-the-job training will equip you to carry out the duties of a professional hydrologist. Along the way, you can actively work on cultivating the following skills and characteristics:
Physical stamina is also important for hydrologists, as some of them might need to hike to remote areas over difficult terrain in order to set up monitoring equipment and collect samples.
Undergraduate degree programs in hydrology are few and far between. Instead, aspiring hydrologists can earn an environmental science degree. This degree program focuses on environmental health issues and their remediation.
The curriculum will vary from one school to the next. In general, however, environmental science students typically study the following topics:
Students may have the opportunity to complete a capstone project during their senior year. This is a culmination of their environmental science knowledge. Aspiring hydrologists should select a topic pertaining to water resources.
During the course of their studies, undergraduate students typically have opportunities to take elective classes. Students should consider taking courses in computer literacy, environmental law/governmental policy, life sciences, mathematics or earth sciences to bolster their core curriculum. A communications class would also be a good idea, as hydrology scientists must be able to communicate their findings accurately, and they may occasionally be called upon to give presentations.
Within the hydrology field, there are options for specializing. Hydrologists tend to specialize in a component of the hydrologic cycle or in a particular water source. For instance, some hydrologists specialize in the evaporation of water and its journey to the atmosphere.
The most common hydrology specializations are as follows:
The typical daily job description for a hydrologist will vary depending on their specialization, employer and current projects. In general, however, a hydrologist may do any of the following tasks:
The job of a hydrologist requires both independent and collaborative work. Hydrologists frequently coordinate their work with environmental science technicians, biologists, engineers, other scientists and public officials. For instance, a hydrologist might connect with an elected official to discuss water management plans for a city, or the hydrologist might work with a biologist to assess the effects of water pollution on local wildlife.
