Validating 137Cs Resampling Approach by Comparing with Conventional Erosion Plot Measurements: An Example of Cultivated Site in Italy

This chapter presents a case study from Italy providing the validation of 137Cs method versus the data from erosion plots. This is a unique study from site where the long-term erosion rates were measured at erosion plots and also 137Cs sampling was done two times. It is the only one such study site worldwide. Therefore, it is presented here as a separate chapter. It should be understood as an example how should the 137Cs resampling study be designed and how the 137Cs method should be validated versus the data on soil erosion rates obtained by conventional erosion measurements. This resampling study was done in seven major methodological steps which were described in detail, each step separately. This is an example of optimal approach how to apply the 137Cs resampling method. The resulting data are interpreted by both key resampling approaches (SRA and TRA). However, one such study cannot be sufficient for validation of 137Cs resampling method. It rather should provide a guidance for other authors on the optimal direction of further research in future.
