10. Permeability Of Soil: Pressure, Elevation and Total Heads

The chapter discusses the permeability of soil, including the concepts of pressure, elevation, and total heads affecting water flow through the soil's interconnected pores. Various factors, including soil type and particle size, determine permeability, which is essential for understanding groundwater movement in different soil conditions. Additionally, Darcy's Law provides a foundational equation for quantifying fluid flow in saturated soils.
