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

* Draw a flow net for flow in an anisotropic medium, showing the correct relationship of flow lines and equipotential lines.

* Draw a flow net for flow in an inhomogeneous medium, showing the correct relationship of flow lines and equipotential lines.

* Draw a flow net showing the correct relationship of equipotential lines and flow lines to the locations of lakes and streams.

* Describe the meaning of the term "potentiometric surface" and tell how it differs from "water table".

* Explain the differences and similarities between flow nets drawn in plan (map) view and flow nets drawn in cross section.

* Using a plan view flow net, draw a flow net for the same system, but in cross section.

* Explain the difference between a conceptual model, an analytical model, and a numerical model for ground water flow.
