Physical properties of sand with various ranges of particle size.

Sand classification	Particle size ranges (mm)	Bulk density (g/cm^3)	Porosity	Saturated conductivity (cm/s)
Medium sand (MS)	0.315∼0.63	1.99	0.25	2.1e − 3
Coarse sand (CS)	0.63∼1.25	1.72	0.35	3.5e − 3
Very coarse sand (VS)	1.25∼2.50	1.59	0.40	5.2e − 3
