Abstract

The hypothesis of this study is that the consistently observed bias for soil erosion models to over-predict low measured rates and under-predict large measured rates is due, at least in part, to the fact that the models are deterministic in nature, and the measured data has a significant random component for which the models cannot account within the deterministic framework. A simplified, synthetic example is presented to illustrate in a general manner the basic nature of the concept. The concept is further tested and verified on a set of 3007 measured soil erosion data pairs from storms on natural rainfall and run-off plots using the best possible, unbiased, real-world model
