  1. 2. is an organism that can live in an environment that offers very low levels of nutrients.
  2. 4. is a watercourse constructed to carry water from a source to a distribution point far away.
  3. 6. of a lake or other body of water is rich in nutrients and so supporting a dense plant population, the decomposition of which kills animal life by depriving it of oxygen.
  4. 8. is a barrier that stops or restricts the flow of surface water or underground streams.
  5. 11. is a hydrologic process, where water moves downward from surface water to groundwater.
  6. 13. having a moderate amount of dissolved nutrients — compare eutrophic, oligotrophic.
  7. 14. is a confined aquifer containing groundwater under positive pressure.
  8. 16. are mainly artificial structures—such as pavements that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops. Soils compacted by urban development are also highly impervious.
  9. 18. is a way to skip the soil, sub in a different material to support the roots of the plant, and grow crops directly in nutrient-rich water.
  10. 19. an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.

  1. 1. is a barrier used to regulate or hold back water from a river, lake, or even the ocean.
  2. 3. is the process of removing salts or other minerals and contaminants from seawater, brackish water, and wastewater effluent
  3. 5. aquifers
  4. 7. occurs in an aquifer when groundwater is pumped from a well.
  5. 9. is a body of rock and/or sediment that holds groundwater.
  6. 10. is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall.
  7. 12. is a ridge of sediment deposited naturally alongside a river by overflowing water.
  8. 15. table is an aquifer whose upper water surface (water table) is at atmospheric pressure, and thus is able to rise and fall.
  9. 17. intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences.
