We review departures from classical definition consider following phenomena: perched inverted tables, gas bubbles within ‘saturated’ below tables dual (and multiple) porosity discuss some different methods for measuring position their relative practicalities, how to avoid measurement errors, such those associated with hydrological instrument response times. question whether remains useful concept, conclude does, citing examples groundwater resource management table's use an indicator soil aeration. In concluding discussion we identify precautions can be taken ensure appropriately measured interpreted. This article protected copyright. All rights reserved.
