Saturation overshoot as a basis for emergent flow phenomena in unsaturated homogeneous porous media
Fürst, T. ; Vodák, R. ; Šír, Miloslav ; Tesař, Miroslav
Understanding and description of fluid motion in unsaturated porous media rates among the most challenging and still not fully resolved problems. Traditionally, porous media flows were described by the continuum mechanics apparatus [1]. The continuum mechanics based models lead to partial differential equations which are mathematical formulations of the balance of mass, momentum, and energy. The most celebrated model is the so called Richards’ Equation (RE) [2]. Other continuum models (see [3], [4] and the reference and discussion therein) are various extensions built on similar principles as the RE.
