HYDRUS-1D Tutorial Book Examples

CSIRO HYDRUS-1D Tutorial Book (Rassam et al., 2018)
Description of Tutorial 1 adapted for Version 5 of HYDRUS
This tutorial book provides a series of example problems for version 4.16 of HYDRUS-1D, a software package for simulating water, heat and solute movement in one-dimensional variably saturated media.The objective of this introductory HYDRUS-1D tutorial is to give HYDRUS-1D users a first hands-on experience with the HYDRUS-1D software package and to familiarize themselves with the overall organization of the HYDRUS-1D graphical user interface, including the main input and output dialog windows.
- Example problems include variably-saturated water flow in single- and multi-layered soil profiles with and without root water uptake.
- Both short- and long-term climatic boundary conditions are considered, with a focus on calculating soil water balance and groundwater recharge.
- Subsequent examples deal with basic advective-dispersive solute transport without solid-liquid interactions, as well as more advanced contaminant transport problems involving linear or non-linear equilibrium sorption reactions and chemical non-equilibrium processes described using one-site sorption kinetics.
- Physical non-equilibrium (mobile-immobile water type) solute transport is also discussed, as well as the combined effect of physical and chemical non-equilibrium effects on solute transport (i.e., a mobile-immobile type model with two-site sorption in the mobile zone).
- Two inverse modelling examples consider one-step and multi-step outflow.
- The final example is about coupled heat movement and reactive solute transport.
