Modeling variably saturated flow in the vadose zone is of vital importance to many scientific
fields and engineering applications. Richardson–Richards equation (RRE, which is …

Topographic and climatic changes are the main causes of abrupt flooding in tropical areas. It
is the need to find out exact causes and effects of these changes. Numerical modeling …

Accurate modeling of variably saturated flow (VSF) in fractured porous media with the
discrete fracture-matrix (DFM) model is a computationally challenging problem. The …

Energy performance of an earth-air heat exchanger (EAHE) at a shallow depth (< 2 m) is
sensitive to climatic conditions and thermo-physical characteristics of the surrounding soil …

Numerical solution of the Richards' equation (RE) in variably saturated soils continues to be
a challenge due to its highly non-linear behavior. This is particularly true as soils approach …

Runoff generated by heavy rainfall in natural catchment area and caused by ditch clogging
in artificial structure increases the instability of the slope. The effects of runoff are usually …

In natural environments, fluid density and viscosity can be affected by spatial and temporal
variations of solute concentration, for example, due to saltwater intrusion in coastal aquifers …

Abstract In this paper, 2-dimensional, hydro-mechanically coupled finite element analyses
are conducted to assess the performance of an engineered barrier, constructed from natural …

A novel, non-invasive imaging technique is proposed that determines 2D maps of water
content in unsaturated porous media. This method directly relates digitally measured …

Richards's equation describes steady-state or transient flow in a variably saturated medium.
For a medium having multiple layers of soils that are not aligned with coordinate axes, a …
