Transport of heavy metals in contaminated soils can cause groundwater pollution. In the present study Hudrus one dimensional software was used for nickel metal transfer from soil to groundwater. Concentrations of Ni was considered in wastewater and sludge as boundary conditions on the flow of incoming water, the concentration of Ni was considered in leaching water as the outlet boundary. Considering the equilibrium model Crank Nicholson and Galerkin finite element by software Haydrus. Concentration changes of Ni was simulated over irrigation period. For this purpose the software Haydrus numbered 1 to number of soil layers, Depth of 100 cm, the depth of groundwater. Time period of irrigation was 150 days. Distribution curves of Ni concentrations in the soil profile shows the experimental results with computational results obtained from the model are similar. And it can be applied in order to determine the concentration distribution of metals in the non- unsaturated zone soil and anticipated arrival time to a specified depth. It can be used to control metal concentrations in the soil and groundwater.
