Abstract

This paper presents the results of a 3 year field study examining bank erosion and channel change on the Daintree River, Australia. Three different methods were employed : 1) erosion pins were used to assess the influence of riparian vegetation on bank erosion, 2) bench-marked cross-sections were used to evaluate annual changes in channel width and 3) historical aerial photos were used to place the short term data into a longer temporal perspective of channel change (1972-2000). The cross-section data were compared against modelled SedNet bank erosion rates, and it was found that the model underestimated bank erosion and was unable to represent the variable erosion and accretion processes that were observed in the field data. The reach averaged bank erosion rates were improved by the inclusion of locally derived bed slope and discharge estimates
