Across
  1. 2. specific & identifiable source of pollution
  2. 7. pollution of well water due to heavy pumping in coastal areas
  3. 9. the speed at which the water in the river is flowing
  4. 15. occur when discharge exceeds channel capacity
  5. 17. sinking of ground due to overpumping
  6. 19. excess of nutrients that leads to dead zones in bodies of water
  7. 21. a stream feeding a larger stream or a lake
  8. 22. pollution spread over large area & difficult to identify; runoff
  9. 23. how much water a river is carrying
  10. 27. impermeable layer that slows/prevents water movement
  11. 28. how well water can move
  12. 29. the process by which water on the ground surface enters the soil
  13. 31. current that flows parallel to the shore
  14. 33. where freshwater from rivers and streams mixes with salt water from the ocean
  15. 35. High tide is highest, Low tide is lowest
  16. 37. where the river opens into a larger body of water
  17. 38. a circular current; there are 5 major examples
  18. 41. the elevated boundary separating areas that are drained by different river systems
  19. 42. a vegetated area near a stream, usually forested, which helps shade and partially protect the stream from the impact of adjacent land uses
  20. 45. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land
  21. 49. area where water fills
Down
  1. 1. the headwaters of a river or stream
  2. 3. a rapid change of temp with depth in the ocean
  3. 4. % of total volume of rock or sediment
  4. 5. the movement and filtering of fluids through porous materials
  5. 6. unsaturated area
  6. 8. open spaces
  7. 10. safe to drink
  8. 11. permeable, saturated rock layer that holds groundwater
  9. 12. area where groundwater intersects with the surface
  10. 13. the process of water movement through a plant
  11. 14. cold water flows upward to replace warm surface water blown out to sea by offshore winds
  12. 16. flat area along a river subject to flooding
  13. 18. path of the river
  14. 20. water table
  15. 24. water flows under natural pressure without pumping
  16. 25. Rhythmic movement that carries energy through the ocean; generated by wind
  17. 26. upper limit of the zone of saturation
  18. 30. a mixture of fresh and salt water
  19. 32. an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel
  20. 34. how we express salinity
  21. 36. a barrier constructed to hold back water and raise its level, forming a reservoir used to generate electricity or as a water supply
  22. 39. High tide is lower than usual, Low tide is higher than usual
  23. 40. the total amount of solid material dissolved in water
  24. 43. Curve in a stream
  25. 44. a triangular area at the mouth of the river where deposition occurs
  26. 46. water held underground in the soil or in pores and crevices in rock
  27. 47. consists of pore space
  28. 48. ecosystem where roots of plants are under water at least part of the year. Examples include marshes and bogs
