Formatted abstract
This study documents the current spatial distribution of areas impacted by water erosion and characterises sedimentation processes in the Lort and Young Rivers. Aerial photography from 2007/8, field data collection and statistical modelling were used to map hillslope and channel water erosion across the full extent of the Lort and Young Rivers catchment that feeds into Stokes Inlet. Multiple models were trialled; the final models selected were constructed using a classification tree modified to reflect field observations. This method was found to perform best when evaluated with independent validation data, and the environmental drivers used for mapping reflect the processes noted as probable important factors in the field. A limited number of sites were field verified, but it was not possible to visit a sufficient number of sites to use field data to drive the hazard modelling process.
