Effects of Contact Angle on the Hysteresis Effect of Soil-Water Characteristic Curves during Dry-Wet Cycles

Table 2

Four groups of samples contact angle measured values.

Type of contact angle	Specimen number				Extreme value
	S1	S2	S3	S4
Advancing angle	53.2°	53.9°	55.4°	51.7°	55.4°
Receding angle	39.7°	39.8°	40.6°	37.8°	37.8°
