- Abstract:
-
Composite fingerprinting, one of the most important method for sediment sources, is extensively used due to its accuracy, ubiquity and simpleness. Composite fingerprinting follows three steps for study on sediment sources. The first step is to classify and identify potential sediment sources within catchment and collect soil samples from the potential sediment sources and sediment samples from catchment outlet. The second step is to screen the optimal combination of fingerprints. The third step is to calculate the relative ration of each potential source. This paper introduces the development of composite fingerprinting by analysis of the steps of sediment sources using composite fingerprinting, reviews the methods of reliability test and summary of research object, and lays the emphasis on screening the optimal combination of fingerprints and the numerical mixing model.
