MODFLOW-USG Flow & Transport Modeling with GMS

Course Description

The groundwater modeling training course by Aquaveo is designed as a hands-on, application oriented training course. The course will provide the attendees with the knowledge and tools necessary to solve groundwater modeling problems quickly and efficiently. The course begins with a review of groundwater modeling concepts and then attendees immediately begin building groundwater models. A series of lectures and instructor led exercises will be presented on using GMS with MODFLOW, MODFLOW-USG, PEST, MODPATH, MT3DMS, borehole data, and GIS data. Attendees will learn how to generate numerical models from high-level conceptual models constructed with GIS tools.

Course Requirements

Participants may be required to provide their own computer with the following specifications:

  • Windows XP, Vista, 7 or 8 operating system
  • 1 GB RAM (2 GB recommended)
  • CPU: GMS software is CPU intensive. Some models and utilities such as Parallel PEST can take advantage of multiple processor cores simultaneously.
  • Graphics Card: For all display features to be enabled, OpenGL 1.5 or higher must be supported. The use of a dedicated graphics card is strongly recommended. Integrated graphics can result in significantly reduced performance and may not support some visualization features.
  • 1024x768 resolution (1280x1024 or higher recommended)
