OVERVIEWCOURSE DESCRIPTIONPROGRAMME

The strain on water resources, both in terms ofquantity and quality in southern Africa, requires
increasingly accurate estimates of water andsolute fluxes in unsaturated porous media(vadose zone) in numerous settings. Theseinclude:• infiltration and uptake in agriculture(water and solutes);• irrigation and drainage applications;• flow through earth dams;• hydraulic and solute fluxes throughwaste impoundments and covers;• local hillslope vadose zone responses;• groundwater-surface water interactions.

The course begins with a detailed conceptual andmathematical description of water flow and solutetransport processes in the vadose zone, followed
by a brief overview of the use of finite element
techniques for solving the governing flow andtransport equations. Special attention is given to
the highly nonlinear nature of the governing flow
equation. Alternative methods for describing andmodeling the hydraulic functions of unsaturated
porous media are also described.

Day 1

Numerical modeling is becoming an increasingly
important tool for analyzing these complex
problems. This course is designed to familiarize
participants with the principles and mathematicalanalysis of variably-saturated flow and transport
processes, and the application of state-of-the-art
numerical codes to site-specific subsurface flow
and transport problems.

TARGET AUDIENCE
The course is intended for graduate students,
researchers and professionals wishing to expand
their knowledge of water flow, contaminanttransport and solute reactions on variablysaturated porous media.

The course introduces a new generation ofWindows-based numerical models for simulatingwater, heat and/or contaminant transport invariably-saturated porous media. These include
the HYDRUS-1D and HYDRUS (2D/3D) codes.
In addition participants will use the RETC
program for optimizing input hydrauliccharacteristics.
"Hands-on" computer sessions will provide
participants an opportunity to become familiar
with the Windows-based RETC, HYDRUS-1Dand HYDRUS-2D/3D software packages.
Emphasis will be on the preparation of input datafor a variety of applications. Calibration will bediscussed and demonstrated by means of bothone- and two-dimensional inverse problems. In
addition participants will be introduced to thePHREEQC-2 and HP1 models for simulating
biogeochemical fate and transport in unsaturatedflow.
