ABSTRACT
Previous field observations using high capacity tensiometers (Ridley et al., 2003) have used ‘‘spot’’ measurements where the tensiometer has been placed in contact with the soil to take a suction reading at a particular time, i.e. the tensiometer was not left in place to take continuous readings with time. Cui et al. (2008) have used high capacity tensiometers for the continuous measurement of suction but their system does not allow installation of multiple tensiometers at different depths at the same location. The system reported in this paper provides multiple tensiometers at different depths as well as the possibility of taking continuous readings with time from each tensiometer. In the proposed system, the tensiometers can also be easily removed if required for re-saturation or replacement.
