Numerical modeling is becoming an increasingly important tool for analyzing complex problems involving subsurface multiphase flow, contaminant transport, and remediation. This course covers subsurface multiphase fluid flow modeling concepts and techniques using the multi-dimensional multiphase flow code TOUGH2/T2VOC (with a new graphical user interface for input/output manipulation and visualization). Topics include the development of conceptual models for vadose zone flow and transport, flow and interphase partitioning of nonaqueous-phase liquids (NAPLs) mixtures in the saturated and unsaturated zones, NAPL-contaminated sites, simulation of remediation techniques, and how to apply the models to effectively solve realistic problems associated with these conceptual models. Participants will acquire a working knowledge of the principles and numerical analysis of multiphase flow and transport processes, and the application of state-of-the-art numerical codes to site-specific subsurface flow and transport problems. Additional information on the codes may be accessed via the internet (http://www-esd.lbl.gov/TOUGH2/).

This course is intended for individuals with some modeling experience or course work. The course begins on Friday (19th) shortly after the MODFLOW 2003 workshop ends. Course sessions are from 8:00 AM to 5:00 PM on Saturday (20th), and 8:00 AM to noon on Sunday (21st).

This short course will present approaches and modeling tools for solving realistic subsurface multiphase-flow problems related to vadose-zone and saturated-zone transport and remediation. The course begins with a detailed conceptual and mathematical description of multiphase fluid flow and interphase partitioning of organic chemicals between phases. The TOUGH2/T2VOC numerical codes are used on PCs and workstations. Topics that will be addressed include:

• Formulation of conceptual models for flow problems.
• Determining an appropriate model grid design for various problems.
• Selecting and incorporating appropriate boundary conditions.
• Use of hydrologic field or lab data for model input.
• Simulation of subsurface flow and transfer of heat and mass (air, water, and chemicals).
• Simulation of selected remediation techniques.

A new version of T2VOC for NAPL mixtures, TMVOC, is to be released soon. If possible, this version will be included in the course applications. "Hands-on" computer sessions will provide participants an opportunity to become familiar with the TOUGH2/T2VOC software packages. Emphasis will be on the preparation of input data for a variety of applications such as those listed above. The new window-based GUI "Petrasim" will be used for data input and output visualization.

COURSE AUDIENCE

This course is intended for practicing geohydrologists, engineers, and ground-water professionals who wish to build upon existing modeling capabilities. This course will provide insight into nuances and multiple approaches to solving realistic field problems using the TOUGH2/T2VOC model. It is assumed that the participant understands the principles of ground-water modeling and the basic fundamentals of soil physics and hydrogeology. This understanding would be based on prior course work, practical experience, or previous application of groundwater flow models.

User's guides for TOUGH2 and T2VOC will be supplied to participants. The manuals contain several documented examples, some of which will be discussed in the class.

The tuition fee for this course does not include the TOUGH2/T2VOC codes for use outside the course. Course participants who wish to use the codes after conclusion of the short course must obtain a license from the Department of Energy's Energy Science and Technology Center (ESTSC). ESTSC's web address is:(http://www.osti.gov/estsc/).

Dr. John McCray is a faculty member of the IGWMC and an Assistant Professor of Geological Engineering at Colorado School of Mines. He has been practicing and teaching applied modeling in the academic and geohydrologic-consulting arena for 10 years. Dr.McCray has published several journal papers using T2VOC. He has authored over 60 documents including refereed journal articles, book chapters, symposium abstracts, and reports relevant to groundwater contaminant transport and remediation.
