HYDRUS is a software package for simulating water flow, heat, and solute transport in variably saturated porous media (soils). The Mater.in file is an input file for HYDRUS used when soil hydraulic properties are defined by tabular data (look-up tables) rather than analytical functions. It contains discrete data points for water content (θ), pressure head (h), hydraulic conductivity (K), and optionally soil hydraulic capacity (C) = dθ/dh. See Table 12.14 in the user manual. This tool validates the format of your Mater.in file and visualizes the hydraulic property curves.
Paste the content of Mater.in into the text box below and click the “Check” button.
