This test was performed two times using each kind of water. The average of cohesion and friction angle with distilled, half saline and saline water are 0.078, 0.108 and 0.107 kg/cm2 and 14.8, 15.8 and 15.2 degrees respectively. The results indicate that salinity has not an important effect on shear strength parameters. However cohesion and friction angle have increased with half saline and saline water. This result is compatible with those of the studies performed by Di Maio and Fenelli, 1994; Alamdar 1999 and Tiwari et al , 2005. The reason for the low changes in cohesion and friction angle may be the low clay content in soil and the low increase of these parameters with water salinity can be due to increasing attractive force between particles and establishing bounds between them
