Aug 29 and 31 Pre-Aug 29 class: Read Ch 2 of Anderson and Woessner Section 2.1 Focus on the general form of the governing equation: (Eq 2.2 in the text) -how was the equation derived? Don’t worry as much about the “mechanics” of the derivation as the assumptions contained in the derivation. Consider: Validity of Darcy’s law Assumption that mass conservation = volume conservation What is a “representative elementary volume” or REV? How big or small is it? What does it mean to align the axes with the principle directions of hydraulic conductivity? Is it always possible? - Think about how would Eq 2.2 simplified for: o 1D flow o 2D flow (the “aquifer” viewpoint)

Look over Box 2.1 on spreadsheet modeling. During the remainder of Aug 29 th class, you will get started on Assignment 1, focusing on developing 1D finite-difference approximations and implementing them in Excel. On the 31 st , we will discuss your results from Parts I and II of the homework and move on to an example of transient flow (Part III)....
