23rd European Meeting of Environmental and Engineering Geophysics
Short Course: A practical introduction on how to apply ground-based transient electromagnetic (TEM) for mapping of groundwater resources?
This course will demonstrate how easy and efficient the transient electromagnetic method is for mapping of groundwater resources. Many believe the method is considered difficult to understand and complicated to operate. However, new, robust and very powerful instruments, together with modern and automatic processing software, have been developed in recent years making the methods easy and intuitive to use. In a few weeks, entire watersheds can be mapped from the surface down to 300 m.
Attendees for the course are practitioners and beginners to transient electromagnetic. The technical background can be geophysics, hydrology, engineering, geology, etc. Focus is on mapping of groundwater resources but if you are working with salt/fresh water problems, geotechnical problems or mineral exploration the course is also highly relevant to you.
In the course, we will:
- Discuss how the method and data processing works from a theoretical point of view;
- Go into detail with best and most efficient field practice;
- Discuss how to choose transmitter–receiver configuration to resolve a given target;
- Demonstrate modern equipment and relate the design of this equipment to field practice (we bring equipment);
- Made hands-on exercises in data processing, data inversion and presentation of results;
- Show examples and discuss choice of instrument configuration for mapping of salt/fresh water boundaries and aquifers.
Participants are requested to bring a laptop.
Instructors will be:
Anders Vest Christiansen (Aarhus University, Denmark)
Esben Auken (Aarhus University, Denmark)
Thue Bording (Aarhus University, Denmark)
