Recently, the nonlinearity continuation method has been used to numerically solve boundary value problems for steady-state Richards equation. The can be considered as a predictor-corrector procedure with simplest form which applied date having trivial, zeroth-order predictor. In this article, effect of more sophisticated predictor technique is examined. Numerical experiments are performed finit...

A discrete fracture, saturated-unsaturated numerical model is developed where the porous matrix is represented in three dimensions and fractures are represented by two-dimensional planes. This allows a fully three-dimensional description of the fracture network connectivity. Solute advection and diffusion in the porous matrix are also directly accounted for. The variably-saturated flow equation...

This study introduces PoreFlow, a pore-network modeling tool capable of simulating fluid flow and multi-component reactive and adsorptive transport under saturated and variably saturated conditions. PoreFlow includes a variety of modules, such as: pore network generator, drainage simulator, calculation of pressure and velocity distributions, and modeling of reactive solute transport accounting ...
