Chapter 13

Groundwater flow

Darcy's law is described, and some discussion of permeability is given, for various rock or soil types. Dam seepage is studied via the Dupuit approximation, and there is some discussion of the resulting nonlinear diffusion equation. Next, the discussion is broadened to include consolidation, including a little about hysteresis in the compression curves, and then solute dispersivity and heterogeneous porous media are treated. Piping is discussed in the notes, and dual porosity models form the basis of one of the exercises.
