Dempster's Rule of Combination in Soil-Loss Prediction

Soil erosion has long been a major problem to mankind and continues to threaten soil conservation worldwide. To deal effectively with this problem, the first step is to obtain a reasonably accurate prediction of the soil loss. This paper uses an inference procedure to combine soil loss predictions obtained from different methods. The objective of this combination is to minimize the uncertainty associated with the applied techniques. The procedure is applied to several cases to evaluate this procedure, and future developments are discussed. The procedure is performed satisfactorily in test routings on two Nebraska watersheds. A similar procedure will be used in erosion and runoff control evaluation.
