Solution of degenerate parabolic variational inequalities with convection
ESAIM: Modélisation mathématique et analyse numérique, Tome 37 (2003) no. 3, pp. 417-431.

Degenerate parabolic variational inequalities with convection are solved by means of a combined relaxation method and method of characteristics. The mathematical problem is motivated by Richard's equation, modelling the unsaturated - saturated flow in porous media. By means of the relaxation method we control the degeneracy. The dominance of the convection is controlled by the method of characteristics.
