A thorough examination of the accuracy and reliability of this method is conducted across a number of spatial scales and years providing confidence in the method and results. Soil depth is measured across the study catchment providing the first bedrock map of a basalt derived soil catchment. Both soil erosion and soil depth are topographically assessed using a high resolution digital elevation model. Results show that soil depth was strongly correlated with elevation and also wetness indices indicating a strong relationship with soil moisture in soil production. Interestingly bedrock topography was decoupled from surface topography. Erosion rates using the 137Cs method and calibrated against independent field data produced a maximum erosion rate of between 0.8 and 2.9 t ha−1 yr−1 using two different modelling approaches. Even though the erosion rates are low, given a mean soil depth of 0.44 m for the catchment this suggests that soil is being lost at rates greater than production. This highlights the significance of assessing erosion loss in the context of overall soil depth and production rates and that even in areas with what appears to be low soil loss rates, the loss can be higher than production. The findings provide a rationale to examine soil erosion in the context of whole catchment processes, not simply soil loss in isolation to other hillslope and catchment data.]]> Sat 24 Mar 2018 07:41:42 AEDT ]]> A comparison of SRTM and high-resolution digital elevation models and their use in catchment geomorphology and hydrology: Australian examples https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3159 Sat 24 Mar 2018 07:18:14 AEDT ]]>
