Books and computer software applications that I have co-authored are shown to the right. Click the images for more information.

Winter, 2004: A Tradinational-Chinese translation of the book "3D-Groundwater Modeling with PMWIN" is published. Click here for details.

Fall, 2003: The book "Numerical Simulation of Reactive Flow in Hot Aquifers" is published by Springer Verlag. The book deals with the numerical simulation of reactive transport in porous media using the simulation package SHEMAT and Processing SHEMAT.  The latter is based on the version 5.0 of Processing Modflow. SHEMAT (Simulator for HEat and MAss Transport) is an easy-to-use, general-purpose reactive transport simulation code for a wide variety of thermal and hydrogeological problems in two or three dimensions. The enclosed companion CD-ROM contains the software and data for all of the case studies.

Summer, 2003: A comprehensive report "A Survey of Methods for Groundwater Recharge in Arid and Semi-arid regions" is published by the United Nations Environmental Programme. ISBN 92-807-2131-3. The PMWIN 5.1 software is included in the report available for free to the world!

Seer3D is a 3D Visualization application currently under development. It is designed to incorporate data stored in various graphic formats into an informative 3D scene. This image shows an isosurface based on field measured values. The isosuface has been cut through by a cropping tool and the color-filled contours depict the concentration levels within the isosurface. A georeferenced raster image (aerial photo) and a vector graphic saved in the ESRI shapefile format are also displayed for spatial orientation.

2D-Visualization within PMWIN. The site map is loaded from a bitmap file; the model grid from a DXF file. The concentration plume is animated within Processing Modflow.
