12. Actions taken MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 the samples were taken from embankment near Galston finally only one type of sample was measured = Intact Galston clay the samples were taken from embankment near Galston finally only one type of sample was measured = Intact Galston clay

13. General difficulties MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 maybe problem with some financial deposit on the start of secondment for housing (no problem for private company) maybe problem with some financial deposit on the start of secondment for housing (no problem for private company)

14. Outlook of future career MAGIC - Monitoring systems to Assess Geotechnical Infrastructure subjected to Climatic hazards Mid-Term Review Meeting - Brussels, 17 November 2014 A procedure for the measurement of soil electrical conductivity via TDR has been developed, which will be used for testing of intact samples taken from the instrumented ‘benchmark’ sites. A few field combined measurements of water content and electrical resistivity would be sufficient to tune any calibration curve from laboratory experiments on samples of reduced (aggregate) size. General benefit is for good modeling of water content in embankment or dam.
