Abstract

The capabilities of the HYDRUS-1D and HYDRUS (2D/3D) software packages have been substantially expanded since two earlier HYDRUS workshops held in Prague, Czech Republic (March 2008) and Tokyo, Japan (June 2008). Multiple processes were added to both HYDRUS packages, including compensated root water and solute uptake models and triggered irrigation. Computational modules of both packages have been made about 2-3 times faster by using capabilities of advanced processors and compilers, such as using the loop vectorization. Major developments were introduced in version 2 of HYDRUS (2D/3D). This version can now handle for the first time complex, general, three-dimensional geometries, while domain properties, initial conditions, and boundary conditions can be specified on geometrical objects, rather than on the finite element mesh. Completely new modules accounting for processes not available in the standard HYDRUS version were introduced. These new modules include the HP2, C-Ride, DualPerm, UnsatChem, Wetland, and Fumigant modules. These new modules simulate flow and transport processes in two-dimensional transport domains and are fully supported by the HYDRUS graphical user interface. Several processes in these specialized modules of HYDRUS (2D/3D) have been made also part of HYDRUS-1D
