The collection of spatial data on sediment and colloid movement is becoming increasingly important as we seek to constrain environmental models and further or understanding of sediment and colloid transfers through the environment. Recent developments in tracer technology offers the promise of new insights into erosion, transport and deposition processes over a range of scales and timescales - but can this promise be fulfilled?
This session will seek to highlight advances in existing and developing technologies for tracing sediments and colloids in environmental systems. We encourage those working on the use of radionuclides, rare earth oxides, fluorescent particles and other tracers to submit abstracts, as well as those who are using tracing information to constrain or improve process based modelling. While the convenors have experience in land and fresh water systems we also encourage the submission of abstracts from authors working in other environments (air, estuaries, oceans) in order to encourage interdisciplinary cross-fertilisation of ideas.
