The pools that remain in northern Australian rivers during the long dry season provide an important refuge for stream fauna and flora and are often culturally significant. There is a common perception, however, that many of these riverine waterholes are being filled by sands. Changes in land-use upstream and the effects of climate change have been suggested as causes for sand accumulation. This project sought to determine, whether there was evidence for sustained infilling of pools within two north Australian river catchments.

The project was led by scientists at the Australian Rivers Institute (ARI) at Grifﬁth University in Brisbane. They were supported by other scientists from CSIRO Land and Water (in Canberra), the Northern Territory Government and Charles Darwin University.
Andrew Brooks from the ARI was the project leade
