2010-9-10 Soil thermal conductivity measurements describe the soil properties which govern the flow of heat through the soil. The thermal conductivity is defined as the quantity of heat that flows through a unit area in a unit time under a unit temperature gradient. A soil's thermal conductivity is significantly influenced by its saturation and dry density.

2020-12-16 In general, correlations between N-values and soil properties should only be used for cohesionless soils, and sand in particular. Caution should be used when using N-values obtained in gravelly soil. Gravel particles can plug the sampler, resulting in higher blow counts and estimates of friction angles than actually exist. Caution should also
