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
