Progress UpdateData Issues: Data process time
• Identifying start and end reflection points takes time
• 16 permittivity per hour
• c.11520 per station per month
• Currently 4 stations –too many to do this manually!
• Conductivity data is simpler
• Quantity is the same as for permittivity
SOLUTION: Script needed
• Finish and install the remaining two sensors at the clay site at Diddington
• Develop a script to computer analyse the waveforms from the TDR to process the data quickly
• Source a vibracorer and develop a methodology on frequency and locations for coring
• Begin geotechnical laboratory tests on the soil samples from the two sites
