Description The understanding of water erosion processes is essential when predicting the effects of soil
conservation structures aimed to disrupt connectivity in runoff and sediment transport across
the landscape. Experiments (field and laboratory) measuring the overall effect of these
structures and model analysis are usually the techniques used to evaluate their effectiveness.
However, the use of sediment tracers is an attractive tool to complement those technologies
providing insight into the processes acting within the measured area (Guzmán et al. 2013a).
During the last years an erosion tracer methodology based on the application of iron oxides as
magnetite, hematite and goethite to tag the top soil profile has been evaluated and validated in
several laboratory and field experiments (Guzmán et al., 2010, 2013b, 2015). They have been
employed, afterwards, to monitor preferential flows, identify sources of sediments, quantify
medium term erosion rates and to map soil redistribution within agricultural fields due to
erosion and deposition.
