HYDRUS Mater.in Checker

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.

On password management

Remembering multiple complex passwords is difficult. For this reason, many people likely use simple, easy-to-remember passwords or reuse the same password across many sites, even though they know it's not a good practice. This article offers some tips on how to manage your passwords.

When reading foreign texts, having materials formatted so you can check meanings and instantly play audio significantly boosts learning efficiency. On the other hand, manually creating these materials—splitting paragraphs into sentences, adding translations, and embedding playback buttons—is a tedious and time-consuming task.
