Hydrus-1D is a public domain Windows-based modeling environment for analysis of water flow and solute transport in variably saturated porous media. The software package includes the one-dimensional finite element model HYDRUS for simulating the movement of water, heat, and multiple solutes in variably saturated media.

New features of the one-dimensional part of Version 5 of HYDRUS include new modules PFAS, Cosmic, DPU, Particle Tracking, and C-Ride, as well as updated graphical capabilities, such as two-dimensional z-t graphs of selected variables.

The purpose of this technical report is to document the standard one-dimensional computational modules (often referred to as HYDUS-1D) for version 5 of HYDRUS, a software package for simulating water, heat, and solute movement in one-, two-, and three-dimensional variably saturated porous media.

HYDRUS version 5 was released in April 2022 and it merges two previously independent software packages HYDRUS-1D (version 4, for one-dimensional applications) and HYDRUS (2D/3D) (version 3, for two- and three-dimensional applications).
