Modeling Root-Soil Water Movement and Solute transport (R-SWMS)

R-SWMS (Javaux et al., 2008) is a numerical model for simulating solute transport and water flow in and between the soil abd the plant system.

Modeling Root-Soil Water Movement and Solute transport (R-SWMS)

R-SWMS (Javaux et al., 2008) is a numerical model for simulating solute transport and water flow in and between the soil and the plant systems. Based on the flow and transport equations in the 3D soil matrix and within the 3D root xylem network, it simulates the uptake of solute and water by plant roots for a growing plant. Three-dimensional root growth is function of environmental conditions (soil strength, temperature) and plant parameters (gravitropism, sensitivity to strength, etc.).

The code main programming language is Fortran 90. It has originally been created from the model of Clausnitzer and Hopmans (1994), and thus contains similar same water flow and solute transport routines than SWMS3D (1995). Since then, it has been developed by several contributors through PhD and master theses.

A publication list referring to R-SWMS can be found here.

A more technical description of the cade can be found here.

The R-SWMS code is freely available on demand.
