Daily Objectives #10 (September 27, 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
  • 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.
  • Explain the difference between hydraulic conductivity and permeability.
  • Describe a lab method for measuring hydraulic conductivity.

Today's Agenda:

v Reminder: Exam #1 is on Oct. 4 (one week from today).

v Properties of Porous Materials: Define these properties of porous materials: hydraulic conductivity and permeability.   Explain the difference between them.  Write formulas to express each quantity.  Give a typical range of values for each property in various rocks and sediments.

v Measuring Hydraulic Conductivity and Permeability:  For Homework #3, devise a test for measuring hydraulic conductivity.  Using that protocol, measure the hydraulic conductivity of two samples of sediments, and write a lab report as per the instructions  given on the homework page.   We will spend about 80 minutes of the class period on this!
