Objectives #7 (September 18,
the end of today's class, you
should be able to do the following:
Properties of Porous Materials:
- Define the following terms, using appropriate units of
specific yield, specific retention, hydraulic conductivity.
- Write formulas defining each of the properties in terms of
volumes and in terms of the other properties.
- Characterize rocks and sediments in terms of their
porosity, effective porosity, specific yield, and specific retention,
giving typical ranges of values of these properties for each type of
rock and sediment.
v Debriefing previous classes' activities:
v Properties of Porous Materials: Define these properties of porous
specific yield, specific retention. Write formulas to express
each quantity. Write a formula that relates specific retention
and specific yield to porosity.

- In small
the responses to the assessment question on transferring water from a
rain barrel to a trash bin.
v Water Flow--Lab Explorations, continued:
here for an MSWord copy of the instructions):
v Further experimentation on water flow
forget...you are working with a group to investigate some specific
aspect of water flow. Your experimental setup/results/conclusions
should be ready to present by Thursday (Sept. 20).
