aModified California test numbers to be converted to SPT equivalent.
^bNumerical results for Consolidated Undrained (CU) triaxial tests and Vane Shear (VS) tests were not provided.
^cUnconsolidated Undrained (UU) triaxial tests were only available from the USACE [17] data.
^dCPT logs represent continuous measurement of parameters.
