Abstract
Release of alluvial suspended sediment from channel bank erosion since European settlement has Resulted in the formation of a colmation layer along the upper Hunter River trunk stream at Muswellbrook, eastern Australia. We use X-ray diffractometry (XRD) to determine the mineralogical Signature of a riverbed colmation layer and floodplain sediment sources across this 4,480km² catchment. This sediment tracing technique allows us to construct a picture of how suspended sediment supply operates in this system. Understanding the spatial variability in sediment supply
Is critical for the development of catchment action plans that treat the causes of sediment source And delivery problems rather than just the symptoms.
