The analysis as well as the numerical simulation of density driven flow in porous media is still a challenging task. Whereas thorough theoretical investigations are limited to special situations, the numerical treatment, especially of real-world problems, requires special numerical techniques. In this talk we focus on two aspects, which are relevant in this context. The first deals with the design of robust multigrid solvers for problems with high spatial anisotropies. In the second part, we investigate (a class of) saltwater intrusion problems. Their solutions give rise to a special type of numerical problemis. Numerical results are presented confirming the theoretical considerations.
