: Soil is a three-phase system consisting of solid particles, water, and air. Key parameters include void ratio , porosity , and degree of saturation .
: These include particle size distribution (sieve analysis) and Atterberg limits (liquid limit and plastic limit), which describe the plasticity and consistency of fine-grained soils. Principles of Geotechnical Engineering
), often modeled by the . Coarse soils like sand rely mainly on friction, while fine-grained soils like clay rely on cohesion. : Soil is a three-phase system consisting of

Geotechnical engineers categorize soils to predict their engineering behavior:
: Defined by Darcy's Law , this principle describes how water flows through soil pores. Managing seepage is critical to prevent "piping" failures in dams and embankments.
