PRODUCT

FEFLOW

Groundwater hydrologists or hydrogeologists 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 these questions requires specific field information and a general understanding of hydrogeological processes. Nature is not simple, yet even simple tasks require state-of-the-art supporting tools. Groundwater models provide a quantitative framework for synthesising field information and for conceptualising hydrogeologic processes. Models are used as a tool to assist consultants and engineers in getting possible answers to a specific groundwater problem.

In this course, we will provide you with practical examples of how you could benefit from the FEFLOW Python Programming Interface to answer groundwater-related questions in a cost-effective manner.

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) allow 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 large-scale modelling. Application areas include water management, mine water, saltwater intrusion, geothermal energy and variably saturated media.

IS THIS COURSE RIGHT FOR ME?

This course is right for you if:

• You are a consultant, engineer, hydrogeologist or geologist 
• You have a basic understanding of hydrogeological concepts
• You have a certain understanding of the modelling workflows in FEFLOW
• You have been working with FEFLOW and are looking to speed up your modelling workflows with the FEFLOW Python Programming Interface

WHAT ARE MY EXPECTED OUTCOMES?

Upon completion of the course you will be able to:

• Work with the FEFLOW Python Programming Interface
• Adapt the Python training scripts for your own project needs
• Operate FEFLOW models through the FEFLOW Python interface (open, save and run files)
• Work with selections with the help of Python scripts, e.g. accessing selection items
• Understand the use of FEFLOW callbacks in Python to interact with the FEFLOW engine during the simulation
• Work with boundary conditions and budget calculations.
• Run particle tracking methods outside FEFLOW
• Create simple visualisations in Python using FEFLOW modelling results

HOW WILL I LEARN?

Each module includes videos and materials that you need for model examples. 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.

Final remarks

INSTRUCTOR

DR. CARLOS RIVERA VILLARREYES, DHI GERMANY  
Dipl.-Ing. (FH), Civil Engineering, University of Piura, Peru; MSc, Desert Studies - Water Resources Management, Ben-Gurion University, Israel; PhD, Hydrology, University of Potsdam, Germany

Dr Carlos Rivera Villarreyes works as a Global Product Specialist and Product Manager / Owner 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, geothermal modelling, water quality and nuclear waste decommissioning applications among others. He has carried out several groundwater modelling projects and trained professionals in groundwater modelling around the globe. Dr Carlos is an authorised DHI trainer.

REQUIREMENTS

• Reliable internet connection 
• An installation of the DHI License Management and FEFLOW software 
• If you are not familiar with the 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.

LANGUAGE
Lectures and training material are in English.
