  2. Surface water - Wikipedia

    en.wikipedia.org/wiki/Surface_water

    By reducing ground water pumping, the surface water supplies will be able to maintain their levels, as they recharge from direct precipitation, surface runoff, etc. It is recorded by the Environmental Protection Agency (EPA), that approximately 68 percent of water provided to communities in the United States comes from surface water.

  3. Surface-water hydrology - Wikipedia

    en.wikipedia.org/wiki/Surface-water_hydrology

    Surface-water hydrology is the sub-field of hydrology concerned with above-earth water (surface water), in contrast to groundwater hydrology that deals with water below the surface of the Earth. Its applications include rainfall and runoff , the routes that surface water takes (for example through rivers or reservoirs ), and the occurrence of ...

  4. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and ...

  5. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    Water is important in many geological processes. Groundwater is present in most rocks, and the pressure of this groundwater affects patterns of faulting. Water in the mantle is responsible for the melt that produces volcanoes at subduction zones. On the surface of the Earth, water is important in both chemical and physical weathering processes

  6. Hyporheic zone - Wikipedia

    en.wikipedia.org/wiki/Hyporheic_zone

    The hyporheic zone is the region of sediment and porous space beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water.The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes.

    At around 600 miles wide and up to 6,000 meters (nearly four miles) deep, the Drake is objectively a vast body of water. To us, that is. To the planet as a whole, less so.

  8. Water quality - Wikipedia

    en.wikipedia.org/wiki/Water_quality

    Water collected from depths below the surface will normally be held at the reduced pressure of the atmosphere; so gas dissolved in the water will collect at the top of the container. Atmospheric gas above the water may also dissolve into the water sample.

  9. Upwelling - Wikipedia

    en.wikipedia.org/wiki/Upwelling

    Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton.
