The level of the perched water table in the raised beds, however, exceeded a depth of 0.
In 1997 at Cranbrook, transects of the perched water table were obtained at right angles to interceptor drains.
Prior to the rainfall event (4 September) the depth to the perched water table was about 0.
All the manual observations at Cranbrook of the depth to the perched water table over 3 growing seasons in 1997, 1998, and 1999 and the automated observations in the 2000 season are presented as cumulative frequency distributions in Fig.
This long duration of saturation coincides with the second restricting layer (the pallid zone or pallid soil subsystem), and the second perched water table, coming close to the surface (Fig.
The second perched water table, in the second hydromorphic subsystem on top of the pallid zone, shows a less sensitive, slightly delayed response, caused by the retarding effect on downward movement of water of the relatively impermeable mottled zone above it.
As a consequence, less water flowed down towards the top of the pallid zone, and the perched water table at about 3.
