East Asian Online HYDRUS (September 13-15) and HPX (September 16-17) shortcourses, 2021
Objectives of the HYDRUS Short Course
The short course begins with a detailed conceptual and mathematical description of water flow and solute transport processes in the vadose zone and groundwater, followed by a brief overview of numerical techniques for solving the governing flow and transport equations. Special attention is given to the highly nonlinear nature of the governing flow equations. Alternative methods for describing and estimating the hydraulic functions of unsaturated porous media are also given.
Hands-on computer sessions will provide participants an opportunity to become familiar with the windows-based HYDRUS-1D and HYDRUS (2D/3D) computer software packages, including several additional modules, such as ROSETTA, UNSATCHEM, and the Wetlands module. Emphasis will be on preparation of input data for a variety of one- and multi-dimensional applications such as flow and transport into and through the vadose zone, infiltration from a subsurface source, and two-dimensional leachate migration through the unsaturated zone. Calibration will be discussed and demonstrated with several examples for both water flow and solute transport (using HYDRUS).
Selected advanced HYDRUS topics will be covered during the second part of the course.
Advanced topics will include:
- Coupled movement of water, vapor, and energy (including the surface energy balance)
- Preferential/nonequilibrium water flow and solute transport (using dual-porosity and dual-permeability models)
- Biogeochemical transport and reactions: solute transport of major ions using the UNSATCHEM module
- Modeling flow and transport using a three-dimensional module of HYDRUS (2D/3D)
Objectives of the HPx Short Course
Good knowledge of the HYDRUS modeling environment is a prerequisite for this short course and thus taking the HYDRUS short course first is encouraged..
The short course begins with a detailed conceptual and mathematical description of thermodynamic equilibrium and reactive transport modeling approaches, mostly those related specifically to HP1. This introduction begins with presentation of theoretical concepts of thermodynamic geochemical modeling and is followed by several computer sessions intended to familiarize students with the geochemical code PHREEQC-3. The structure of the thermodynamic database, the definition of the composition of the (initial) solutions, and selected examples of equilibrium reaction path modeling are discussed.
The importance of coupling solute transport with geochemical reactions is illustrated using multiple examples. Basic elements of coupling the advection-dispersion equation with geochemical reactions are discussed, especially with respect to the structure of HP1. The first HP1 example illustrates how the two codes (HYDRUS-1D and PHREEQC-2) and their graphical interfaces are used to set up and interpret reactive transport problems solved with HP1.
The next computer sessions focus on chemical processes involving solid surfaces (ion exchange and surface complexation), both for geochemical equilibrium modeling (PHREEQC-2) and reactive transport (HP1). The final sessions will introduce kinetic reactions into geochemical systems. First, an example is shown how kinetic mineral dissolution or degradation reactions can be included in PHREEQC-3, after which an example is given of a kinetic reaction network in a transport problem.

Instructor of the HPx short Course
Dr. Diederik Jacques is Head of the Engineered and Geosystems Analysis (EGA) unit of the Institute of Environment, Health and Safety (EHS) of the Belgian Nuclear Research Centre (SCK•CEN) in Mol, Belgium. He received a B.S. and M.S. in Bio-engineering land and forest management, a Master of Statistics, and a Ph.D. in soil physics, all from the Catholique University of Leuven, Belgium. His expertise is in modeling water flow and solute transport in unsaturated porous media including characterizing spatial variability and estimating parameters. His current focus is on coupling unsaturated water flow, solute transport and geochemical reactions, including the development and testing of the coupled code HPx, application to (long-term) solute transport in soils and interaction between different systems (clay-concrete and or soil-concrete). He is involved in safety and performance analyses of surface and deep geological waste disposal sites, and radiological site and environmental remediation, including supporting calculations using reactive transport models.
