Hydrologists study water and how it moves across and beneath the Earth's surface. They examine rivers, lakes, groundwater, precipitation, and water quality to understand how water systems work and how they are affected by natural events and human activity. Their work helps communities and organizations manage water resources, assess floods and droughts, protect water quality, and plan for changing water conditions.
A bachelor's degree in hydrology, geology, environmental science, earth science, or a related field is typically required. Some positions, particularly those involving advanced research or specialized work, may require a master's or doctoral degree.
Water is essential to every community and ecosystem, making hydrology an important field for the future. Hydrologists help address challenges involving water quality, flooding, drought, groundwater, water supplies, and changing environmental conditions. Advances in monitoring technology, computer modelling, and data analysis are also creating new ways to understand and manage the world's water resources.
Hydrologists work in offices, laboratories, and outdoor field locations. They may collect water samples, operate monitoring equipment, study rivers and streams, analyze data, and use computer models to understand and predict water conditions. Fieldwork can involve travelling to remote locations and working outdoors in changing weather conditions.
