  20. Evaporation while falling Precipitation Evapotranspiration Evaporation

  21. The Water Cycle on Long Island http://www.scwa.com/

  22. Can we influence our groundwater? www.euwfd.com

  23. FQ: What can we do to protect our ground water? ----

  24. What are the affects of sediments on Groundwater?

  25. Porosity All the pore space

  26. Which sample has more porosity? Same

  27. Size vs. Porosity Increasing Porosity Increasing Particle Size

  28. Sorting of Sediments (unsorted) (sorted)

  29. Sorting vs. Porosity Increasing Porosity Poorly Sorted Well Sorted Sorting

  30. Which sample has more porosity?

  31. Shape vs. Porosity Increasing Porosity Flat Round (Clays) Shape (sands)

  32. Which sample has more porosity?

  33. Permeability

  34. Which sample is more permeable?

  35. Size vs. Permeability Increasing Permeability Increasing Particle Size

  36. Which sample is more permeable?

  37. Which sample is more permeable?

  38. *As permeability increases, -

  39. Infiltration

  40. Size vs. Infiltration Faster Infiltration Slower Large Small Size

  41. Slope vs. Infiltration Faster Infiltration Slower Gentle Steep Slope
