Falling head permeability tests on Till deposits from the Vale of Eden, England - supplementary report including new data

This report describes permeability tests carried out on twenty three samples of glacial till obtained from boreholes drilled in the Vale of Eden area in Cumbria, England. The results of 134 initial tests are also documented in Internal Report IR/13/034 (ibid.). Further samples were obtained in September 2013 and results of an additional 76 tests on seven additional samples are reported here. The report outlines the testing procedure and presents the results of the permeability tests. The laboratory permeability values of till soils from the Moreland and Pow Focus Catchments ranged from 10-5 to 10-10 m/s, suggesting permeability is variable, with Medium Low to Impermeable soils.
