Grimsel Training Centre: In-situ Testing and Hydraulic Characterisation in URL Course

Nagra offers a 6-day workshop at the Grimsel Test Site on in-situ rock characterisation in underground rock laboratories (URLs).  The participants will get hands-on experience on URL
field research methods such as handling drill cores, borehole fluid logging and hydraulic testing.  The testing will be done in existing boreholes in low permeable and fractured rock.

The course aims to impart both theoretical and practical knowledge.  The acquired skills shall help the participants in planning, tendering and carrying out field experiments in URLs.  To a certain degree, the imparted topics are translatable to site investigations in general.

Theoretical blocks and related field work will alternate in short intervals. The daily activities will be structured as follows:

1. Short lecture on theory of methods to be applied during the day.
2. Field work using specialised equipment.  Acquire high quality field data.
3. Instruction on how to analyse the acquired test data.
4. Analysis of results (individually or in small groups).
5. Discussion of results (all).

Further details are available in the course announcement and on the Grimsel website.
