The soil properties and parameters can be broadly classified as
1)Physical
2)Engineering
3)Index
Physical soil properties include specific gravity, density, particle size and distribution and water content.
The water content represented by w of a soil sample is defined as the weight of free water in the sample expressed as a percentage of its dry weight.
The degree of saturation S is defined as the ratio of the volume of free water to its total volume of voids Vv
n=Vv/V
where n is the Porosity defined as the ratio of void volume to the total volume V of soil.
