The soil of the meander plain has the strongest texture contrast (Mitchell).
The modelling suggests that the palaeochannels may be directly connected to the prior streams commonly associated with the meander plain.
In the western third, the stratigraphic nature of the soil and sediments associated with the old meander backplain and meander plain can be inferred.
In the east, the samples are generally associated with the texture contrast (duplex) Mitchell profile class of the Old Alluvium meander plain, while in the centre the root-zone is characterised by the cracking clay profile classes (Mullah, Snake, and Buddah profiles) that characterise the Old Alluvium backplain.
This includes: duplex profiles (Mitchell Profile Class of the Old Alluvium meander plain and Byron of the Trangie Cowal pedoderm); prior streams and infilled channels; uniform heavy clays (Mullah, Snake, and Buddah of Old Alluvium backplain) and silt-textured profiles (Macquarie of the Contemporary Macquarie pedoderm).
The larger silt content indicates sediments were deposited under a lower energy regime than the Old Alluvium meander plain.
In brief, the coarser sediments associated with the Old Alluvium meander plain in the west are characterised by intermediate-small [[sigma].
Again the coarser sediments of the Old Alluvium meander plain, Trangie Cowal, and Contemporary Macquarie pedoderms are characterised by small readings ([less than or equal to]100mS/m), while the larger readings (> 100 mS/m) coincide with the Gin Gin Hills.
In the west, and with respect to the EM38h, the coarse sediments of the Old Alluvium meander plain are characterised by intermediate-small [[sigma].
Conversely, the EM38 suggests the presence of more conductive sediments and given the location indicates the presence of texture contrast soil profiles associated with the Old Alluvium Meander Plain.
This may represent the location of a palaeochannel among the generally clayier part of the regolith associated with the Old Alluvium meander plain.
Various components of the Old Alluvium pedoderm, including the meander plain and infilled channels, are apparent.
