A numerical groundwater flow model can be the most efficient and effective tool to understand the groundwater flow regimen and obtain reasonable information about relationships among the geological environment and surface flow. Having a code for groundwater modeling is not enough, it is necessary to know both the modeling platform and understand the physical processes it wants to reproduce, and in this particular case, the water dynamics of the hydrogeological system.
This course develops the main functions and applications of the latest version of the MODFLOW 6 groundwater modeling code through the ModelMuse interface, both developed by the United States Geological Survey (USGS). These versions of MODFLOW and Model Muse includes innovative tools for the construction and simulation of hydrogeological models, mainly highlighting the incorporation of the discretization option for discretized by vertices grids (DISV).
Objectives
The development of the course will allow the application of groundwater modeling tools to analyze regional and local flow. Participants will learn to build model on MODFLOW 6 and analyze the results.
In this course the student will learn:
ModelMuse environment and tools for modeling.
Know the potential of Model Muse to build MODFLOW 6 models.
Conceptualization criteria, grid design and boundary conditions.
Modeling of particle tracking with MODPATH.
Calibration and transient simulation of numerical models.
Analyze water balances and head distributions.

Part 1:
Configuration of MODPATH in a steady-state model with quadtree refinement.
Forward and backward particle tracking simulation applied to a model with general-head boundary conditions and wells.
Part 2:
Configuration of MODPATH in a transient-state model.
Forward and backward particle tracking simulation applied to a model with wells with different pumping rates and a river that interacts with a nearby well
Session 5: Three-dimensional anisotropy
Configuration XT3D which enables a full 3d anisotropy in MODFLOW 6 models, this is applied trough angles in a 3D model.
Part 1:
Creation of a model in steady-state with three-dimensional anisotropy applied in 2 axis that creates whirls.

Part 2:
Three-dimensional steady-state simulation with quadtree refinement and three-dimensional anisotropy distributed in 2 axis of the grid.
Session 6: Regional model
This session is focused to create a model for represent a regional groundwater model based on a basin, rivers and topography. Apart of that, we will develop the comparative of head observed and simulated.
Construction a three-dimensional steady-state model with a basin that delimits the active zone placed throughout the extension of the grid.
Use graphic objects and external shapefiles to apply to boundary conditions such as recharge, evapotranspiration, and rivers.
Application of head observations and post-processing of results with Python
