Abstract
Assessing sediment production and transfer on a range of time and spatial scales is indispensable to understand Earth's surface dynamics and landscape evolution processes. Linking and quantifying these processes from erosional source areas through to depositional sinks is crucial to apprehend down-system signal propagation and modification. Cosmogenic nuclide analyses have proven incredibly useful to investigate a variety of geomorpic landforms and processes along such sediment conveyors on 103-106 year timescales, but have to date largely focused on steep landscapes.
This thesis utilises cosmogenic 10Be and 26Al abundances, measured in exposed bedrock, hillslope soils, and modern stream sediments, to investigate and link sediment production mechanisms and transfer dynamics in three post-orogenic, low-relief catchments (Finke, Macumba, Neales) covering >100,000 km2 of the Eyre Basin in arid central Australia.
