Soil Permeability Estimation
Many important applications in the cleanup of contaminated soil and in the production of petroleum from oil fields require the understanding of soil structure and prediction of fluid flow patterns. Subsurface flow is dependent on a number of factors, with one of the primary ones being the permeability field. Permeability is a measure of how easily fluid moves through the porous medium at a point, and it varies spatially. In this chapter, we treat permeability as a constant at a point, but in more detailed applications it may be tensor-valued to account for the fact that soil structure can be directional and so fluid may flow more easily in some directions than in others.
