Hydrologists study the occurrence, distribution, movement, and properties of water as a solid, liquid, and vapor, as it cycles through surface waters, the atmosphere, and the surface layers of the Earth. Hydrological inquiry involves almost all of the physical sciences, including physics, chemistry, geology, soil sciences, and meteorology, as well as engineering, the social sciences, and life sciences.

The Section’s scientific activities are administered by ten technical committees: Erosion and Sedimentation, Groundwater, History of Hydrology, Large-Scale Experimentation, Policy Sciences, Precipitation, Remote Sensing, Surface Water, Unsaturated Zone, and Water Quality. Thus members of the Hydrology Section study a variety of water-related issues and concerns such as the relationship of land-based surface water processes to weather and climate, including floods, droughts, and erosion; groundwater flow and the remediation of contaminated groundwater; and the characteristics and causes of water quality conditions.
