Formatted Abstract/Summary

High resolution side scanning sonargraphs of subaqueous terrain can be used to interpret detailed morphology and gross textural forms.

The Brisbane River, an ancient watercourse, presently occupies a channel which probably dates back to the earlier stages of the Pleistocene, possibly to the late Pliocene.

Sonargraphs of the River from the City (Brisbane) upstream to the confluence with a major tributary, the Bremer River, reveal a sequence of alternating gorges and reaches, interpreted as knickpoints corresponding to stillstands of earlier sea levels.
