Hydrologists are scientists who study the distribution, movement, and properties of water on, below, and above the Earth's surface. They examine the hydrological cycle, including rainfall, rivers, lakes, soils, groundwater, and atmospheric moisture, and assess how natural processes and human activities influence water availability, quality, and flood risk. Their work supports sustainable water resources, environmental protection, and climate change adaptation.

Hydrologists use a combination of field measurements, laboratory analyses, and computer-based modeling. Field tasks may include measuring streamflow, sampling water quality, mapping aquifers, and installing sensors. Modeling tools incorporate hydrological, hydraulic, and statistical models, Often with geographic information systems (GIS) and remote sensing. Subfields include surface hydrology, hydrogeology, ecohydrology, and hydrometeorology, as well as watershed and groundwater management.

Education and training typically lead with a bachelor's degree in hydrology, geology, civil or environmental engineering, or a related field, followed by graduate study for research or specialized roles. Many hydrologists work in government agencies, water utilities, environmental consulting firms, universities, or research institutes. Professional credentials, such as licensure for consultancies or certifications in water quality, may be pursued depending on jurisdiction.

Hydrologists play a central role in water resource planning, flood and drought risk assessment, contaminant transport studies, and the design of infrastructure such as dams and wastewater systems. They inform policy, land-use planning, and climate resilience efforts, balancing human needs with ecosystem health. The field is increasingly interdisciplinary, integrating ecology, meteorology, and data science to address complex water challenges.
