  • Stream gauge
    A stream gauge, streamgage or gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water.
  • Acid rain
    Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH).
  • Drainage basin
    A drainage basin or catchment basin is an extent or an area of land where all surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another body of water, such as a river, lake, reservoir, estuary, wetland, sea, or ocean.
  • Fresh water
    Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams.
  • Ice
    Ice is water frozen into a solid state.
  • Salt lake
    A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre).
  • Transpiration
    Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
  • Water resources
    Water resources are sources of water that are useful or potentially useful.
  • Wind wave
    In fluid dynamics, wind waves, or wind-generated waves, are surface waves that occur on the free surface of oceans, seas, lakes, rivers, and canals or even on small puddles and ponds.
  • Seiche
    A seiche (/ˈseɪʃ/ SAYSH) is a standing wave in an enclosed or partially enclosed body of water.
  • Capillary action
    Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
  • Salinity
    Salinity is the saltiness or dissolved salt content of a body of water (see also soil salinity).
  • Streamflow
    Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle.
  • European Watershed
    The Main European Watershed is the drainage divide which separates the basins of the rivers that empty into the Atlantic Ocean, the North Sea and the Baltic Sea from those that feed the Mediterranean Sea, the Adriatic Sea and the Black Sea.
  • Injection well
    An injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer.
  • Soakage (source of water)
    A soakage, or soak, is a source of water in Australian deserts.
  • Drainage in New Orleans
    Drainage in New Orleans, Louisiana, has been a major concern since the founding of the city in the early 18th century, remaining an important factor in the history of New Orleans today.
  • Freshwater environmental quality parameters
    Freshwater environmental quality parameters are the natural and man-made chemical, biological and microbiological characteristics of rivers, lakes and ground-waters, the ways they are measured and the ways that they change.
  • Precipitation types
    In meteorology, "precipitation types" can include the character or phase of the precipitation which is falling to ground level.
  • Water content
    Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood.
  • Water balance
    In hydrology, a water balance equation can be used to describe the flow of water in and out of a system.
  • Fluid conductance
    Fluid conductance is a measure of how effectively fluids are transported through a medium or a region.
  • List of floods
    This is a list of major floods.
  • Outline of hydrology
    The following outline is provided as an overview of and topical guide to hydrology: Hydrology – study of the movement, distribution, and quality of water on Earth and other planets, including the hydrologic cycle, water resources and environmental watershed sustainability.
  • Snow hydrology
    Snow hydrology is a scientific study in the field of hydrology which focuses on the composition, dispersion, and movement of snow and ice.
  • Arctic sea ice decline
    Arctic sea ice decline is the sea ice loss observed in recent decades in the Arctic Ocean.
  • Relief ratio
    The relief ratio is a number calculated to describe the grade of a river or stream.
  • Oxygenation (environmental)
    Environmental oxygenation can be important to the sustainability of a particular ecosystem.
