Problem Classificationvatives in spatial coordinates and first order derivatives in time. Whereas time derivatives appear linearly, spatial derivatives often have a non-linear form. Frequently, systems of partial differential equations occur rather than a single equation.

Multiphase Flow in Deformable Porous Mediassible and incompressible fluids) we also apply the Richards approximation, which is valid for most cases of infiltration in soils. We assume isothermal conditions. For additional information the reader should refer e. g. to Bear & Bachmat (1990) and Lewis & Schrefler (1998).

1.2.3 Orbital motion of the earth, such as mass, momentum, and energy are conserved during the considered process at all times. Any physical system can be completely determined by this conservation properties. In contrast, other quantities such as pressure or entropy do not obey conservation laws. The only additional information con

1.1 Origin of the earth in the solar system,bove a certain Reynolds number. Below values of the so-called critical Reynolds number .. the flow is smooth and adjacent layers of fluid slide past each other in an orderly regime. This regime is called laminar flow. At Reynolds numbers larger than the critical value a complicated series of physica
