  7. INTRODUCTION What is permeability? A measure of how easily a fluid (e.g., water) can pass through a porous medium (e.g., soils) water Loose soil - easy to flow - high permeability Dense soil - difficult to flow - low permeability

  8. INTRODUCTION What is deference betweenPorosity and Permeability? • Illustration of pore and pore channels in a rock. • These two figures have the same porosity (same pore space). • In the figure to the right the pore channels are closed and the permeability is zero.
