Hydrology studies the movement, distribution, quality, and management of water on Earth and other planets.
Hydrology is the scientific study of water on Earth and other planets, focusing on its movement, distribution, quality, and management. It examines the water cycle as water moves into, through, and out of drainage basins, including processes such as precipitation, evaporation, infiltration, groundwater flow, surface runoff, and river discharge. Hydrology also considers water resources and the sustainability of catchments and drainage basins. The scope of hydrology includes surface water hydrology, groundwater hydrology or hydrogeology, and marine hydrology, along with specialized fields such as hydrometeorology, ecohydrology, chemical hydrology, isotope hydrology, water-quality science, and hydroinformatics. Hydrologists use field measurements, remote sensing, statistical analysis, and computer models to understand water systems and address practical issues such as flood and drought risk, water supply, irrigation, pollution, environmental conservation, infrastructure design, and sustainable water-resources management. Oceanography and meteorology are related fields but have broader primary focuses on oceans and the atmosphere, respectively.
Hydrology studies the movement, distribution, quality, and management of water on Earth and other planets.
A central subject of hydrology is the water cycle, including precipitation, evaporation, infiltration, groundwater flow, surface runoff, and drainage into oceans.
The discipline covers surface water, groundwater, marine water, drainage basins, water quality, and interactions between water, land, the atmosphere, and living organisms.
Hydrologists apply observations, scientific analysis, remote sensing, and mathematical modeling to solve water-related environmental, engineering, and resource-management problems.
Major applications include water-supply planning, irrigation, flood and drought prediction, pollution assessment, infrastructure design, and sustainable water-resources management.
The scientific study of the movement, distribution, quality, and management of water on Earth and other planets.
The continuous circulation of water among the atmosphere, land surface, soil, groundwater, rivers, lakes, oceans, and living organisms.
The study of hydrologic processes and water flows occurring at or near Earth's surface.
The study of the occurrence, movement, storage, and quality of water beneath Earth's surface.
The branch of hydrology concerned primarily with groundwater and its movement through geological formations.
An area of land in which precipitation and other water flows drain toward a common outlet such as a river, lake, or ocean.
The planning and regulation of water availability, quality, demand, and infrastructure to support human needs and environmental sustainability.
A scientist or professional who studies water systems and applies hydrologic knowledge to environmental, engineering, and resource-management problems.
