A finite element method for the solution of two-dimensional transient dispersive-convective transport of nonconservative solute species in fractured porous media is presented. A two-nodal point one-dimensional transport element for fractures is developed which provides a number of advantages relative to conventional fracture representation by two-dimensional continuum elements. To eliminate the oscillatory behavior of convective-dominated transport which is a more likely occurrence in fracture, an efficient one-dimensional upstreaming method along with a two-dimensional method is implemented. Validity of the numerical scheme is established by comparison with existing one- and two-dimensional analytic solutions. 21 refs.
