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

* Describe the relationships between and among the following properties of porous materials:

                > porosity and effective porosity;
                > specific retention and specific yield;
                > specific yield and effective porosity; and
                > specific yield, specific retention, and porosity.

* Give the typical range of values of porosity, specific yield, and specific retention of different types of porous materials, using the correct units of measurement.

* Describe what is meant by the hydraulic conductivity and the permeability of a porous material, and explain the difference between the two.

* Give typical ranges of the value of hydraulic conductivity and permeability of different types of porous materials, using the correct units of measurement.

* List the kinds of rocks and sediments that are generally considered aquifers.

* List the kinds of rocks and sediments that are generally considered aquitards.

* Sketch a cross section illustrating the generalized hydrostratigraphy of northeastern Illinois.
