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 ]]> Catchment reconstruction - erosional stability at millennial time scales using landscape evolution models https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27141 Sat 24 Mar 2018 07:33:01 AEDT ]]> Prediction of vertical soil organic carbon profiles using soil properties and environmental tracer data at an untilled site https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27735 137Cs and ²¹⁰Pb were assessed with the aim of better understanding the transport processes which produce the observed vertical distribution of SOC. While no consistent relationship was found between SOC and soil physical properties significant relationships were found between the distribution of SOC and the environmental tracers, ¹³⁷Cs and ²¹⁰Pb. Finite element simulations based on a diffusion/convection/decay model showed that the transport of ¹³⁷Cs and ²¹⁰Pb down the soil profile is likely to be driven by the same (primarily diffusive) processes. The same model used in conjunction with plant input and decay data generated from the RothC-26.3 soil carbon model revealed that transport of SOC down the soil profile, while also a diffusion process, was significantly slower indicating that different processes and/or pathways are involved in SOC transport at this site.]]> Sat 24 Mar 2018 07:27:46 AEDT ]]> Karst morphology and cave sediments as indicators of the uplift history in the Alpi Apuane (Tuscany, Italy) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3322 5 m thick flowstones whose top-beds have an age exceeding the limits of U/Th alpha spectrometric dating (>350 ka). Cave morphology and chronological constraints obtained from speleothems suggest that an important uplift event occurred during the Middle Pleistocene following a period of tectonic standstill of probable latest Early Pleistocene age. Active spring caves close to present-day valley floors contain speleothems whose ages exceed 100 ka, implying that no significant downcutting of the seaward valleys, and consequently no tectonic uplift, has occurred during Late Pleistocene.]]> Sat 24 Mar 2018 07:23:17 AEDT ]]> Brittle deformation events in the Lambert Glacier region (East Antarctica): insights into the tectonic control on the formation and evolution of the Lambert Graben https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3506 Sat 24 Mar 2018 07:22:49 AEDT ]]> Geomorphology and surficial sediments of the southeast Australian continental margin https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3364 Sat 24 Mar 2018 07:19:00 AEDT ]]> A methodology for calculating the spatial distribution of the area-slope equation and the hypsometric integral within a catchment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4824 Sat 24 Mar 2018 07:18:53 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 ]]> Channel head location and characteristics using digital elevation models https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3160 Sat 24 Mar 2018 07:18:14 AEDT ]]> A qualitative and quantitative evaluation of experimental model catchment evolution https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3164 Sat 24 Mar 2018 07:18:13 AEDT ]]> Gully position, characteristics and geomorphic thresholds in an undisturbed catchment in northern Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3161 Sat 24 Mar 2018 07:18:12 AEDT ]]> The design of post-mining landscapes using geomorphic principles https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:3166 Sat 24 Mar 2018 07:18:09 AEDT ]]> Holocene record of Tuggerah Lake estuary development on the Australian east coast: sedimentary responses to sea-level fluctuations and climate variability https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24116 Sat 24 Mar 2018 07:11:43 AEDT ]]> Predictors of soil organic carbon in agricultural pastures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33302 Mon 23 Sep 2019 13:15:44 AEST ]]> Principles of Soilscape and Landscape Evolution https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47555 Mon 23 Jan 2023 12:57:25 AEDT ]]> Potential increase in coastal wetland vulnerability to sea-level rise suggested by considering hydrodynamic attenuation effects https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31419 Mon 02 Mar 2020 14:10:50 AEDT ]]> Assessing digital elevation model resolution for soil organic carbon prediction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45415 2 = 0.37–0.51), however not in the finer-scale data (model R² = 0–0.21). Variable importance was calculated from the modelling process, with elevation (as a surrogate for climate) being the main driver at the catchment-scale. In the finer scale datasets, topographic variables linked to soil redistribution were more important. As a result, SOC estimation methods using coarse resolution DEM data and large-scale sampling may be limited in capturing the effect of topography, having implications for SOC management and modelling.]]> Fri 28 Oct 2022 09:49:08 AEDT ]]>
