Estimating Relative Density of Sandy Soils

Soils and Foundations, 2006
ABSTRACT The applicability of three previous empirical correlations proposed for estimating relative density of sandy soils based on the SPT N-value, effective overburden stress and soil gradation characteristics was investigated in the present study by using a data base of relative density obtained from high quality undisturbed samples of fine to ...

Modeling soil bulk density at the landscape scale and its contributions to C stock uncertainty [PDF]

, 2012
Soil bulk density (Db) is a major contributor to uncertainties in landscape-scale carbon and nutrient stock estimation. However, it is time consuming to measure and is, therefore, frequently predicted using surrogate variables, such as soil texture ...
