We consider an initial boundary value problem for a nonlinear differen
tial system consisting of one equation of parabolic type coupled with
a n x n semi-linear hyperbolic system of first order. This system of e
quations describes a model of compressible miscible displacement of n
+ 1 chemical species in porous media, in the absence of diffusion and
dispersion. In one-dimensional space, we construct a global weak solut
ion with bounded total variation for the concentration. (C) Elsevier;
