| Abstract: | The numerical methods for the mathematical model for the problem of the pollution in groundwater with mixed boundary are considered.A mixed finite element method is adopted for the pressure equation,the concentration of the contimination is approximated by a standard Galerkin method,Optimal error estimates in L 2 norm are obtained for the continuous time schemes. |
