Using some additive materials to gypsum soil can increase its compressive strength and erosion and make it fit for civil projects in irrigation networks. In this study, (Journal No. 268., 2003) five levels of cement (5, 8, 10, 12 and 15 % to dry soil) and three levels of micro silica (0, 5 and 10 % cement) were added to the local soil. The processing of soil samples were conducted in two temperature (27 and 400C) and their compressive strength was studied and analyzed via SAS statistical software. In the present research, the best combination, with the minimum addition and a high compressive strength, was reached by adding 10% cement and 10% micro silica to the soil. In order to evaluate the sample’s erosion potential, it was exposed to water jet plane in four angles (Ө = 0,30,60, 90), five speeds (V = 2, 4, 6, 8 and 8.64 m/s) and three times (T =4,8 and 12 hr) and the highest weight loss erosion (dw) was observed between the speed of 4 to 8 m/s and the time of 8 hours later in a horizontal state (0 Ө =). .
