dc.description.abstractRadionuclides are often used in sediment studies, but rarely are they paired with Remote Sensing and Geographic Information Systems (GIS). The two used together provide a useful holistic research tool, radionuclides Pb-210, Cs-137 and Pu-239+240 indicate the relative contribution of topsoil and subsoil to sediments, while remote sensing and GIS indicate the location of sediment sources. This method is trialed on the Kambaniru River Catchment in East Sumba, Indonesia. The Kambaniru Weir is an important source of agricultural water for rice production in the poorest region of Indonesia. This weir and many others in the region are rapidly filling with sediment, impacting on agricultural production. To reduce sediment loads it is essential to understand sediment sources. This is also the first reported application of Pu 239+240 as a topsoil tracer in Indonesia with promising preliminary results indicating a strong correlation between Pu239+240 and Cs-137 concentrations.en_AU
