Daily Objectives #11 (October 2, 2007)                                        Dr. Sanders

By the end of today's class, you should be able to do the following:

v Properties of Porous Materials
  • Define the following terms, using appropriate units of measurement: hydraulic conductivity and permeability, and explain the difference between them.
  • Characterize rocks and sediments in terms of their hydraulic conductivity and permeability, giving typical ranges of values of these properties for each type of rock and sediment.
  • Define the terms aquifer and aquitard, giving examples of rocks/sediments that might compose each.
  • Explain what makes water flow.
  • Define the term hydraulic gradient.
  • Find total hydraulic head at any point in a system of tubes and buckets (e.g. a siphon) and correctly predict which way flow will proceed (if at all).
  • Use Darcy's Law by applying it to a permeameter system.
