Abstract:
... MODFLOW SURFACT is a state-of-the-art simulator that utilizes vadose zone flow and transport equations to provide practical solutions to the analysis of flow and contaminant transport at various levels of complexity and sophistication as needed for site evaluation and closure. The variably saturated flow equation can be solved with standard retention functions or with bimodal or multimodal relativ ...

Abstract:
... Smoothed particle hydrodynamics (SPH) models were used to simulate unsaturated flow in fractures with complex geometries. The SPH is a fully Lagrangian particle-based method that allows the dynamics of interfaces separating fluids to be modeled without employing complex front tracking schemes. In SPH simulations, the fluid density field is represented by a superposition of weighting functions cent ...

4. A set of analytical benchmarks to test numerical models of flow and transport in soils

Author:
Vanderborght, J.; Kasteel, R.; Herbst, M.; Javaux, M.; Thiery, D.; Vanclooster, M.; Mouvet, C.; Vereecken, H.

Abstract:
... Accurate model predictions of water flow and solute transport in unsaturated soils require a correct representation of relevant mechanisms in a mathematical model, as well as correct solutions of the mathematical equations. Because of the complexity of boundary conditions and the nonlinearity of the processes considered, general solutions of the mathematical equations rely on numerical approximati ...
