 (- this is the same information/materials as the MIT online course on Groundwater Hydrolog in Fall 2005 available from their Open CourseWare program)
 - could be promising, I plan to go through the materials and narrow down which aspects are most pertinent to this study

Here is an outline of the syllabus.

Outline
