| Abstract: | In this paper,a nonlinear hyperbolic-parabolic coupled system is derived so as to describegroundwater quality contamination,A numerical method(mixed finite element and characteristic finite element combined method)is introduced.Two elliptic projections and their error estimates are given,Afull time discrete scheme of the method is presented.Optimal orderestimates in H' are proved for this scheme. |
