Description :
A total of 177 erosion pins was installed at 45 sites on 4 sand-bed streams (Tributaries North and Central, East Tributary and Ngarradj) in the Ngarradj catchment in the Alligator Rivers Region. Bank erosion was measured for up to 3.5 years (start of 1998/99 wet season to end of 2001/02 wet season) at 3 spatial scales : a discontinuous gully, a small continuous channel on an alluvial fan, and three medium-sized continuous channels with riparian vegetation. The AA. compare bank erosion rates between different wet and dry seasons. They determine the influence of bank profile form and channel planform on erosion rates.
