Physical properties of sand samples.

Sand soil	(g/cm^3)	(cm/s)	(%)	(%)	(g/cm^3)
Medium	1.61	1.45 × 10^−2	37.8	10.7	2.59
Fine	1.71	5.59 × 10^−3	34.5	12.5	2.61
Silty	1.79	9.75 × 10^−4	31.0	15.3	2.60

Where is natural density; is permeability coefficient; is porosity; is moisture content; is specific gravity.
