A numerical flow model can be the most efficient and effective tool to carry out these analyzes and obtain reasonable information on the relationships between groundwater components. However, having a modeling tool is not enough, it is necessary to know both the modeling platform and understand the processes it wants to reproduce, and in this particular case, understand 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). This version includes innovative tools for the construction and simulation of hydrogeological models, mainly highlighting the incorporation of the discretization option for discretized by vertices grids.
Objectives
The development of the course will allow the application of these 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.

Trainer
Saul Montoya M.Sc.
Saul Montoya M.Sc. is a Hydrogeologist and Numerical Modeler. Mr. Montoya is a Civil Engineer graduated from the Catholic University in Lima with postgraduate studies in Management and Engineering of Water Resources (WAREM Program) from Stuttgart University – Germany with mention in Groundwater Engineering and Hydroinformatics. Mr Montoya has a strong analytical capacity for the interpretation, conceptualization and modeling of the surface and underground water cycle and their interaction.
He is in charge of numerical modeling for contaminant transport and remediation systems of contaminated sites. Inside his hydrological and hydrogeological investigations Mr. Montoya has developed a holistic comprehension of the water cycle, understanding and quantifying the main hydrological dynamic process of precipitation, runoff, evaporation and recharge to the groundwater system.
Over the last 9 years Saul has developed 2 websites for knowledge sharing in water resources: www.gidahatari.com (Spanish) and www.hatarilabs.com (English) that have become relevant due to its applied tutorials on groundwater modeling, spatial analysis and computational fluid mechanics.
