23rd European Meeting of Environmental and Engineering Geophysics
A practical introduction on how to apply ground-based transient electromagnetic (TEM) for mapping of groundwater resources?
The purpose of the course is to demonstrate how easy and efficient the transient electromagnetic method is for mapping of groundwater resources. By many the method is considered difficult to understand and complicated to operate. However, new, robust and very powerful instruments has together with modern and automatic processing software been developed in the later 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.
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)
- Make hand-on exercises in data processing, data inversion and presentation of results (bring a laptop)
- Show examples and discuss choice of instrument configuration for mapping of salt/fresh water boundaries and aquifers
Attendees for the course are practitioners and new beginners to transient electromagnetic. The technical background can be geophysics, hydrology, engineering, geology ect. 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.
Instructors will be:
- Anders Vest Christiansen, Associate Professor, Aarhus University
- Esben Auken, Professor, Aarhus University
- Thue Bording, Post Doc, Aarhus University
