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

* Competently discuss Article 5: "Site Characterization in Densely Fractured Dolomite: Comparison of Methodsransmissivity Variations in Mudstones", by Maureen Muldoon and Ken R. Bradbury. (Ground Water, Vol. 43, No. 6, p. 863-876.) Discussion leader: Paul.

* Explain what the purpose of a pumping test is, and tell what data are collected in the field during such a test.

* Given a value of the parameter "u" for a pumping test, calculate the corresponding value of the well function W(u).

* Given a value of the parameter "u" for a pumping test, use the well function table in the textbook to find the corresponding value of W(u).

* Plot a graph of W(u) vs. 1/u (the reverse type curve) for Theis curve-matching.

* Plot a graph of field data from a pumping test (drawdown vs. time) and use the curve-matching procedure to find transmissivity and storativity.
