Physical parameters of the core soil samples taken from the 3rd wind inspection hole.

Soil sample no.	Soil sample type	(m)	φ
01	Fine sand	180.60~180.75	0.3106	1.138
02	Silty sand	281.20~281.35	0.3333	1.126
03	Silty sand	352.15~352.30	0.3154	1.079
04	Fine sand	444.15~444.30	0.3674	1.080
05	Fine sand	552.00~552.35	0.2538	1.824
06	Silty sand	560.20~560.35	0.3637	0.981

Note: is the coring depth (m), φ is the porosity, and is the permeability coefficient, 10^-5 m/s.
