Advanced Modelling of Water Flow and Solute Transport in the Vadose Zone: HYDRUS; Skukuza, South Africa, November 2010
OVERVIEW
COURSE DESCRIPTION
PROGRAMME
The strain on water resources, both in terms of
quantity and quality in southern Africa, requires
increasingly accurate estimates of water and
solute fluxes in unsaturated porous media
(vadose zone) in numerous settings. These
include:
 infiltration and uptake in agriculture
(water and solutes);
 irrigation and drainage applications;
 flow through earth dams;
 hydraulic and solute fluxes through
waste impoundments and covers;
 local hillslope vadose zone responses;
 groundwater-surface water interactions.
The course begins with a detailed conceptual and
mathematical description of water flow and solute
transport processes in the vadose zone, followed
by a brief overview of the use of finite element
techniques for solving the governing flow and
transport equations. Special attention is given to
the highly nonlinear nature of the governing flow
equation. Alternative methods for describing and
modeling 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 mathematical
analysis 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, contaminant
transport and solute reactions on variablysaturated porous media. Appropriate CPD points
will be assigned to the course. Participants will be
presented with an attendance certificate and
CPD certificate where relevant.
The course introduces a new generation of
Windows-based numerical models for simulating
water, heat and/or contaminant transport in
variably-saturated porous media. These include
the HYDRUS-1D and HYDRUS (2D/3D) codes.
In addition participants will use the RETC
program for optimizing input hydraulic
characteristics.
"Hands-on" computer sessions will provide
participants an opportunity to become familiar
with the Windows-based RETC, HYDRUS-1D
and HYDRUS-2D/3D software packages.
Emphasis will be on the preparation of input data
for a variety of applications. Calibration will be
discussed and demonstrated by means of both
one- and two-dimensional inverse problems. In
addition participants will be introduced to the
PHREEQC-2 and HP1 models for simulating
biogeochemical fate and transport in unsaturated
flow.
