Description :
This study documents the catchment-wide distribution of river sensitivity and adjustment in the upper Hunter catchment, New South Wales, in the period since European settlement. The spatial distribution and timing of lateral, vertical and wholesale river adjustments are used to assess river sensitivity to change. Parish maps from the 1880s are supplemented by 5 complete sets of aerial photographs (commencing in 1938) to analyse differing forms of river adjustment along 13 river courses. Adjustments have been largely non-uniform and localized, reflecting the predominance of bedrock-controlled rivers which have limited capacity to adjust and are resilient to change. Phases of reach-scale geomorphic adjustment to human disturbance are characterized as a gradient of primary, secondary and tertiary responses.
