Pre-requisites
Ideal preparation for this course consists of Geology 627, 629, and 724. The parts of those courses that are essential for this course, however, might be acquired from other types of courses or experience. I will assume you are familiar with the basic principles of groundwater flow, including the basic groundwater flow equation and relevant hydrogeological parameters. I will also assume that you have had some experience running MODFLOW. It will be helpful if you have run MODFLOW with Groundwater Vistas. If you haven’t, you will need to spend some extra time learning how to work with Groundwater Vistas.
Course Objectives
This course provides an overview of transport theory as applied to groundwater problems, an in-depth look at the numerical transport code MT3DMS, and an introduction to the application of transport models to field problems. MT3DMS is a popular and widely-used 3-D transient transport code, which uses output from the groundwater flow code MODFLOW. Both MODFLOW and MT3DMS are supported by the pre/post-processor Groundwater Vistas. Hence, we will be using Groundwater Vistas as the platform from which to run both MODFLOW and MT3DMS. The MT3DMS code allows for consideration of multiple chemical species when combined with the code RT3D, but we will not use the multi-species option or RT3D during the course.
We will use the excellent and highly readable textbook by Zheng and Bennett (2nd edition, 2002). Dr. Zheng is my former PhD student. He is also the developer of MT3DMS and is now a professor at the University of Alabama.
