This four-day online course alternates theory and practical exercises in order to address the entire modeling process, including the development of conceptual models, construction of the numerical model, calibration, sensitivity analysis and simulations of multiple scenarios. The course presents the theory and practical development of three-dimensional groundwater flow and contaminant transport models using Visual MODFLOW Flex.

Participants will have the opportunity to:

• Verify the practical application of Visual MODFLOW Flex in three-dimensional studies of groundwater flow and transport of contaminants
• Develop three-dimensional numerical models with appropriate grids, parameterization, boundary conditions and local hydrogeological conceptualization
• Create rectangular numerical meshes, meshes with local refinement and unstructured polygonal meshes
• Calibrate models to match observed field data, that is, hydraulic loads, flows and concentrations
• Use MODPATH code to model the tracking of three-dimensional particles for the capture zone delineation
• Use the Zone Budget tool to assess the subregional water balance within the domain of the model, such as the appearance of water in pits, impacts of pumping in rivers, etc.
• Use the MT3D code to model the natural attenuation of contaminants and simulate remediation scenarios.

This course will be provided to all participants:

• Theoretical handout with the material presented in the course
• Handout of practical exercises
• Installer of the most current version of the software
• 15-day training license to use the software
• Certificate of participation.
