Hydrologists study how water moves through rivers, lakes, soil, groundwater, and the atmosphere. They collect and analyze water and environmental data to understand water quality, flooding, drought, groundwater supplies, and changing water conditions. They use computer models, monitoring equipment, and tools such as GIS to help communities and organizations manage water resources.
A bachelor's degree in hydrology, geology, environmental science, earth science, or a related field is typically required. Some positions, particularly advanced research and specialized roles, require a master's degree or Ph.D. Professional registration may also be required for certain geoscience positions, depending on the location.
Hydrologists work in offices, laboratories, and outdoor field locations, where they may collect water samples, monitor rivers and groundwater, and operate scientific equipment. Fieldwork can involve travel, remote locations, and changing weather conditions, while office work often involves analyzing data and developing computer models.
Water management will remain important as communities address flooding, drought, water quality, groundwater supplies, and changing environmental conditions. Hydrologists are increasingly using real-time monitoring, computer modeling, GIS, and data analysis to understand water systems and make better decisions.
