Waterloo Hydrogeologic's COVID-19 Response and Action

MODFLOW-USG Short Course at the MODFLOW & More 2013 Conference

/, Groundwater Modeling, MODFLOW-USG, Visual MODFLOW Flex/MODFLOW-USG Short Course at the MODFLOW & More 2013 Conference


Waterloo Hydrogeologic will be offering a 1-day short course on the theory and fundamentals of MODFLOW-USG (MODFLOW with UnStructured Grids) before the start of the MODFLOW and More 2013 Conference. The course provides a combination of lectures and hands-on exercises that are based on real-world problems, and is intended for anyone that is familiar with MODFLOW family of codes. Visual MODFLOW Flex will be used to build the input files, run the MODFLOW-USG simulation, and analyze and interpret the results. The course will be taught by Sorab Panday, co-author of the MODFLOW-USG code, and Wayne Hesch, Product Manager for Visual MODFLOW.


MODFLOW-USG is much more than just simple nested grids; the new finite volume formulation provides a level of gridding capability that exceeds what most MODFLOW modelers are accustomed to. Developing the right grid is fundamental to having a stable, efficient model, and leveraging the full capabilities of MODFLOW-USG. The first step in creating your unstructured grid is to provide shapes as inputs for the grid design. The shapes take the form of points (well locations), and polylines and polygons representing boundary conditions. An unstructured grid can then be generated with local refinement around these objects, providing for effective, local-scale representation of your wells, observation points, and hydrological features.




In Visual MODFLOW Flex, flow boundaries are designed as shapes with attributes in a grid-independent conceptual model. When it comes time to generate an unstructured grid, these shapes are automatically included as inputs/constraints for the USG design. This approach dramatically facilitates generation of the unstructured grid and locally refining the grid around these features. Complex geological elements are defined as conceptual volumes, representing pinchouts, discontinuities, and perched aquifers, lenses, etc. These objects can serve as inputs for defining the vertical layers, including generation of sub-layers, and populating the finite volumes with the appropriate parameter values. The numerical model is generated through an automated conversion routine, and the MODFLOW-USG package files can be generated and run in minutes. Results can be interpreted in 2D, 3D, tables and charts.
