Hydrologists study how water moves across and through the Earth’s crust. They study how rain, snow, and other forms of precipitation impact river flows or groundwater levels, and how surface water and groundwater evaporate back into the atmosphere or eventually reach the oceans. Hydrologists analyze how water influences the surrounding environment and how changes to the environment influence the quality and quantity of water. They use their expertise to solve problems concerning water quality and availability.
What do Hydrologists do?
Hydrologists typically do the following:
- Measure the properties of bodies of water, such as volume and stream flow
- Collect water and soil samples to test for certain properties, such as the pH or pollution levels
- Analyze data on the environmental impacts of pollution, erosion, drought, and other problems
- Research ways to minimize the negative impacts of erosion, sedimentation, or pollution on the environment
- Use computer models to forecast future water supplies, the spread of pollution, floods, and other events
- Evaluate the feasibility of water-related projects, such as hydroelectric power plants, irrigation systems, and wastewater treatment facilities
- Prepare written reports and presentations of their findings
Hydrologists may use remote sensing equipment to collect data. They, or technicians whom they supervise, usually install and maintain this equipment. Hydrologists also use sophisticated computer programs to analyze the data collected. Computer models are often developed by hydrologists to help them understand complex datasets.
Hydrologists work closely with engineers, scientists, and public officials to study and manage the water supply. For example, they work with policymakers to develop water conservation plans and with biologists to monitor wildlife in order to allow for their water needs.
Most hydrologists specialize in a particular water source or a certain aspect of the water cycle, such as the evaporation of water from lakes and streams. The following are examples of types of hydrologists:
