PRODUCT

FEFLOW

Groundwater hydrologists or hydrogeologist are often asked questions about groundwater flow, aquifer hydraulics, management of water resources, fate of contamination plumes or feasibility of geothermal systems, plus others.

Providing answers to all these questions requires specific field information and a general understanding of hydrogeological processes. Nature is not simple and even simple tasks require state-of-the-art supporting tools. A numerical model provides a quantitative framework for synthesising field information and for conceptualising hydrogeologic processes. The model is used as tool to assist consultants and engineers for getting possible answers to a specific groundwater problem.

This self-paced course will introduce you to the basic concept of groundwater flow modelling using FEFLOW. Specifically, the course focuses on the explaining the differences between the options to solve the groundwater flow. The theoretical part of the course will explain all the necessary information you require to understand the settings in FEFLOW. With a number of hands-on exercises, we will try together all these different flow configurations.

FEFLOW is the most intuitive and comprehensive software package for groundwater and porous media modelling. The software has been extensively used for modelling geothermal installations, including both shallow and deep geothermal systems. FEFLOW has the capabilities to model both open and closed loop geothermal systems at any time resolution. A major advantage of FEFLOW compared to other modelling packages is the fact that FEFLOW can easily implement heterogeneties (hydraulic and thermal parameters), groundwater flow patterns, effect of recharge on temperature, etc.

About FEFLOW

FEFLOW is widely recognised as a comprehensive software package for subsurface flow and transport simulation. FEFLOW’s unique meshing capabilities (structured and unstructured) allows for the highest degree of flexibility to account in detail for the most simple to complex geometrical configurations. The software is used by leading research institutes, universities, consulting firms and government organisations all over the world. FEFLOW’s scope of application ranges from simple local scale to complex largescale modelling. Application areas include water management, mine water, saltwater intrusion, geothermal energy and variably saturated media.

IS THIS COURSE RIGHT FOR ME?

The course has been designed for consultants, engineers, hydrogeologist and geologist with some basic understanding of hydrogeological concepts and geothermal installations. It is not mandatory that you have already carried out numerical simulations. However, it is beneficial if you have certain knowledge of flow simulations in FEFLOW. You can quickly learn about these through the free self-paced course ‘Getting started with groundwater modelling using FEFLOW’.

WHAT ARE MY EXPECTED OUTCOMES?

After completing this course, you will be able to understand all the different options to solve the groundwater flow equation in FEFLOW. You will have learnt:

• To understand the differences between FEFLOW's problem classes: confined, phreatic, free-and-movable and Richards' Equation. 
• To set numerical models with confined conditions
• To set numerical models with unconfined conditions (either Phreatic mode or Free mode)
• To understand situations where the water table exceeds the topography (unconstrained vs. constrained heads)
• To estimate surface runoff driven by FEFLOW's flow constraint options.
• To have a basic understanding about unsaturated-flow modelling.
• To check the model results for flow simulations.

LEARNING METHODOLOGY

Each module includes videos and materials that you need for model examples and quizzes. It will take you around three hours to complete the course at a time that fits your needs and requirements – and from the comfort of your own office, home or any location convenient for you.

Dr. Carlos Rivera Villarreyes works as Global Product Specialist for FEFLOW. Dr. Rivera has profound knowledge of groundwater and unsaturated-zone modelling as well as parameter estimation and uncertainty analysis (e.g., with PEST), all these in the context of mining applications among others. He has carried several groundwater modelling projects and trained professionals in groundwater modelling around the globe.

Dr. Carlos is an authorised DHI trainer.

REQUIREMENTS

• Reliable internet connection of sufficient bandwidth
• An installation of the DHI License Management and FEFLOW software is required for the completion of the hands-on exercises. This will be explained in the Module 1 of the training course.
• If you are not familiar with basic terminology of Hydrogeology, e.g., definitions of aquifer properties (confined/unconfined systems, transmissivity, conductivity, etc.) and principles of groundwater flow (e.g., Darcy Law), it is strongly recommended to do a pre-reading of standard textbooks of Hydrogeology.
