This document provides a progress update from January to June on various installations and data issues related to weather station and soil sampling projects. It highlights the challenges faced in processing permittivity data and proposes solutions, including the development of a script for rapid data analysis. Future work involves completing sensor installations, sourcing equipment, and starting geotechnical laboratory tests.

9. Progress Update Data 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

10. 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 Progress Update Future Work
