The existence of soluble materials is on of the effective parameters in choosing the type and site of the dams. Thus understanding the behavior and mechanism of such materials against different environmental terms as surface and cortical currents and the effect of minerals in water like salts and their effects on soluble materials are necessary. In this paper, solubility tests on samples with gypsum from Marash dam site for different salt percentages have been done. The results show that with the increase of salt and flow rate, the solubility rate increases. With an increase in temperature the gypsum solubility rate increases. In addition, the results indicate that the saturation time for water-soluble gypsum with different rates is less than the results of soluble tests with sodium chloride.
