Formulation of Fully Coupled THM Behavior in Unsaturated Soil

A Fully Coupled THM Double Porosity Formulation for Unsaturated Soils

Behavior of Unsaturated Layered Soil Columns during Infiltration

This paper presents the laboratory test results of vertical infiltration on two soil columns of finer over coarser soils subject to simulated rainfalls under conditions of no-ponding at the surface and constant head at the bottom. The main objectives were to evaluate the effect of rainfall intensity and duration; and to provide experimental evidence for soil water redistribution and hysteresis....

Towards a scalable fully-implicit fully-coupled resistive MHD formulation with stabilized FE methods

This paper explores the development of a scalable, nonlinear, fully-implicit stabilized unstructured finite element (FE) capability for 2D incompressible (reduced) resistive MHD. The discussion considers the implementation of a stabilized FE formulation in context of a fully-implicit time integration and direct-to-steady-state solution capability. The nonlinear solver strategy employs Newton-Kr...

On the Inclusion of Some Biological Impacts and Influences in Coupled Transport Phenomena in Unsaturated Soil

This paper presents a first attempt at the inclusion of some biological impacts and influences in the authors’ continued research on coupled transport phenomena through unsaturated porous media. The work presented here forms an extension to an existing coupled Thermo-Hydraulic-Chemical-Mechanical Model (THCM) to include the biological aspects. The research can therefore be seen as a first attem...

It is a long-lasting challenge in subsurface hydrologic modeling to develop numerically efficient algorithm for coupling unsaturated and saturated flow, especially in regional-scale modeling. In this stud...
