Groundwater Modelling using MODFLOW and Model Muse

Open Course IHE Delft with Hatarilabs


The IHE Delft partnership programme, funded by the Ministry of Foreign Affairs of the Netherlands, supports several activities related to online education development and takes this opportunity to offer the Open Course on Groundwater Modelling using MODFLOW and Model Muse, in cooperation with IHE Delft partner Hatarilabs.

Running from 3-17 August 2020, the course provides basic knowledge about MODFLOW and Model Muse providing the skills to develop, run, and post-process models. The course, run by Saul Montoya from HatariLabs and Hans van der Kwast from IHE Delft includes five webinars on the follwoing dates & times:

  • Monday 3 August, from 18.00 hrs CEST (one hour webinar).
  • Friday 7 August, from 18.00 hrs CEST (one hour webinar).
  • Monday 10 August, from 18.00 hrs CEST (one hour webinar).
  • Friday 14 August, from 18.00 hrs CEST (one hour webinar).
  • Monday 17 Augsut, from 18.00 hrs CEST (one hour webinar).

You can join the event for free here. Additional information is available on the partner website here. 

About the lecturer, Saul Montoya, MSc 

Saul Montoya is a Hydrogeologist and Numerical Modeler. He 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. Saul 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. Saul 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. 

Course objectives

The development of the course consists of practical exercises designed to demonstrate the functionality of MODFLOW applied in groundwater. In this course the student will learn to:

  • Use the ModelMuse environment and tools for modeling.
  • Know the potential of Model Muse to build MODFLOW models.
  • Design a grid and boundary conditions.
  • Build and simulate numerical models.
