Abstract
HYDRUS 1D is an open source, Windows-based software package for simulation of of one-dimensional water movement through variably saturated porous media. The model solves Richards equation for increments of soil depth with thickness and hydrologic characteristics specified by the user. Soil hydrologic characteristics can be assigned based on van Genuchten parameters provided within HYDRUS based on soil texture, or can be specified by the user. The model incorporates a sink term for plant water uptake and provides different options for specifying rooting depth and growth rate. The model provides water content and flux values for observation points at depths specified by the user. The program has a graphical user interface for modifying inputs and visualizing model results, but it is also possible to modify model inputs and visualize outputs by working with the HYDRUS 1D text files, using a program such as R. Using R to modify model input files allows for running many model scenarios in a loop, which streamlines analysis on complex sets of model runs.
