Shear strength is the ability of soil to resist deformation under applied loads, which is crucial for assessing the stability of soil structures.

Permeability is the property that governs the ability of soil to allow water to flow through it, which is important for drainage and groundwater flow analysis.

Elasticity is the property that allows soil to deform under applied loads and return to its original shape upon removal of the load.

Bearing capacity is the ability of soil to support the weight of a structure without undergoing excessive settlement or failure.

Compressibility is the property that governs the ability of soil to change volume under applied loads, which is important for assessing the settlement of structures.

Porosity is the property that describes the void spaces in soil, which can hold water and other fluids.

Erodibility is the property that governs the susceptibility of soil to erosion by water, which is important for assessing the stability of slopes and riverbanks.

Thermal conductivity is the property that governs the ability of soil to conduct heat, which is important for assessing the thermal performance of buildings and underground structures.

Impermeability is the property that describes the inability of soil to allow water to flow through it, which is important for assessing the effectiveness of barriers and liners.

Fertility is the property that describes the ability of soil to provide nutrients and support plant growth, which is important for agricultural and landscaping applications.

Stability is the property that describes the ability of soil to maintain its structure and resist collapse, which is important for assessing the safety of slopes and excavations.

Cation exchange capacity is the property that describes the ability of soil to absorb and release positively charged ions (cations), which is important for assessing the soil's ability to retain nutrients and support plant growth.

Gas permeability is the property that describes the ability of soil to allow gases to flow through it, which is important for assessing the effectiveness of barriers and liners.

Chemical stability is the property that describes the ability of soil to resist chemical degradation, which is important for assessing the long-term performance of structures and the impact of contaminants on soil quality.

Sound permeability is the property that describes the ability of soil to allow sound waves to pass through it, which is important for assessing the effectiveness of noise barriers.
