  2. Groundwater flow - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow

    In hydrogeology, groundwater flow is defined as the "part of streamflow that has infiltrated the ground, entered the phreatic zone, and has been (or is at a particular time) discharged into a stream channel or springs; and seepage water."

  3. Environmental flow - Wikipedia

    en.wikipedia.org/wiki/Environmental_flow

    Environmental flows describe the quantity, timing, and quality of water flows required to sustain freshwater and estuarine ecosystems and the human livelihoods and well being that depend on these ecosystems.

  4. Streamflow - Wikipedia

    en.wikipedia.org/wiki/Streamflow

    Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle.It is one runoff component, the movement of water from the land to waterbodies, the other component being surface runoff.

  5. Spring (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Spring_(hydrology)

    On an average day nearly 303 million US gallons (1,150,000 m 3) of water flow from Big Spring in Missouri at a rate of 469 cubic feet per second (13.3 m 3 /s). Grand Prismatic Spring, Yellowstone National Park, Wyoming. A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface ...

  6. Groundwater - Wikipedia

    en.wikipedia.org/wiki/Groundwater

    Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago [8]).

  7. Groundwater flow equation - Wikipedia

    en.wikipedia.org/wiki/Groundwater_flow_equation

    Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer.The transient flow of groundwater is described by a form of the diffusion equation, similar to that used in heat transfer to describe the flow of heat in a solid (heat conduction).

  8. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    A water flow test, also known as a hydrant flow test, [1] is a way to measure the water supply available at a building site, usually for the purposes of installing a water based fire protection system (fire sprinkler system).

  9. Surface water - Wikipedia

    en.wikipedia.org/wiki/Surface_water

    An inland lake, an example of surface water The entire surface water flow of the Alapaha River near Jennings, Florida going into a sinkhole leading to the Floridan Aquifer groundwater. Surface water is water located on top of land , forming terrestrial (surrounding by land on all sides) waterbodies , and may also be referred to as blue water ...
