HYDRUS is distributed in multiple different versions (Editions / Levels) so that users may acquire only that segment of the software that is most appropriate for their application.
For solute transport, the code supports both (constant and varying) prescribed concentration (Dirichlet or first-type) and concentration flux (Cauchy or third-type) boundaries. The dispersion tensor includes a term reflecting the effects of molecular diffusion and tortuosity.
The unsaturated soil hydraulic properties are described using Genuchten [1980], Brooks and Corey [1964], Durner [1994], Kosugi [1995], and modified Genuchten type analytical functions. Modifications were made to improve the description of hydraulic properties near saturation.
To minimize numerical oscillations upstream weighing is included as an option for solving the transport equation.
In addition, HYDRUS implements a Marquardt-Levenberg type parameter estimation technique for the inverse estimation of selected soil hydraulic and/or solute transport and reaction parameters from measured transient or steady-state flow and/or transport data (only for the standard modules).
