WORKSHOP ON HYDRUS

Workshop Overview

Workshop Description

OnModeling water flow andcontaminant transport in soils
and groundwater using theHYDRUS software packages

Soil and groundwater pollution is an ever-increasing,worldwide problem. In India the groundwater plays ai
importantt t role
l withith 80 % off rurall populationl ti andd 50%of urban population depending on it. Along withintensive use of groundwater, unscientificdevelopment projects and insufficient knowledge ofgroundwater dynamics is creating long-term
problems. Most subsurface pollution problems stemfrom activities involving the unsaturated (vadose)zone between the soil surface and the groundwatertable. The unsaturated zone hence provides the best
opportunities to limit or prevent groundwaterpollution. Once contaminants enter groundwater,ppollution is essentiallyy irreversible, or can beremediated only with extreme costs.

The course begins with a detailed conceptual andmathematical description of water flow and solutet
transportt processes iin th
the vadosedzone, ffollowed
ll d bby
an brief overview of the use of finite element
techniques for solving the governing flow andtransport equations. Special attention is given to thehighly nonlinear nature of the governing flow
equation. Alternative methods for describing andmodeling the hydraulic functions of unsaturated
porous media are also described.
"Hands-on" computer sessions will provide
participants an opportunity to become familiar with
the Windows-based HYDRUS-1D and HYDRUS((2D/3D)) software packages.
pg Emphasis
pwill be on
the preparation of input data for a variety ofapplications, including flow and transport in avadose zone, variably-saturated flow and transport
during irrigation, flow and transport to a tile drain,
and two-dimensional leachate migration from alandfill through the unsaturated zone intogroundwater. Calibration will be discussed anddemonstrated by means of a one-dimensional
inverse problem.

Numerical modeling is becoming an increasingly
important tool for analyzing complex problems
involving water flow and contaminant transport in theunsaturated zone. This course is designed tofamiliarize participants with the principles andmathematical analysis of variably-saturated flow andtransport processes, and the application of state-ofthe-art numerical codes to site-specific subsurface
flow and transport problems.

Registrants are expected to bring their own laptops for hands on exercises with minimum system requirements:
Operating Systems: Windows XP / Windows Vista (32 or 64bit) / Windows 7 (32 or 64bit), X86 CPU with 2 GHz, 2GB RAM, 10 GB total hard disk capacity with about 500 MB reserved for installation, Graphic card witha resolution of 1024 x 768 pixels. No separate computational facility will be provided

SoftwareThe course introduces a new generation ofWindows-based numerical models for simulatingwater heat and/or contaminant transport inwater,
variably-saturated porous media. These include
the HYDRUS-1D and HYDRUS (2D/3D) codes forone-, two- and three-dimensional simulations, andthe Rosetta code for estimating the soil hydraulicproperties (and their uncertainty) from soil texture
andd relatedl t d data.
d t HYDRUS-1DHYDRUS 1D andd HYDRUS(2D/3D) are supported by interactive graphicsbased interfaces for data-preprocessing,
generation of unstructured as well as structured
finite element grid systems, and graphic
presentation of the simulation results. Except for
HYDRUS (2D/3D), all software packages are inthe public domain.
