Abstract: As part of an extensive field programme, the magnitude of errors due to clay remoulding and filter clogging in tests performed in common piezometers is evidenced. Comparisons between variable head and constant head tests suggest that the theories for interpreting the test results do not account properly for the effects of probe geometry. Pending further investigations, variable head tests performed in a non-clogging, self-boring permeameter called PERMAC appear as the most reliable method for the in situ evaluation of permeability in soft clay deposits.
