In this paper, the effect of salts on the determination of the water content and Atterberg limits of sabkha soils has been studied. The tests were performed using distilled water, natural sabkha brine and saline solutions with different salt concentrations. The results indicate that the liquid and plastic limits decrease with pore fluid salinity when the conventional water content procedure is used, but increase when the fluid content method is used. Also, the liquid and plastic limits measured using percussion-cup test and rolling test method are compared to those measured using the fall cone test method.
