Review of research progress in application of fingerprinting method to determination of sediment source
Time: 2019-05-08 | Hits:

Abstract: This paper reviews the new development of fingerprinting method in sediment research. Recent studies have focused on the improvement of the models and the uncertainty analysis of the results. In partic-ular, many methods have been proposed to calculate the relative contributions of sediment sources and to improve the accuracy of the results. At present, there are four new models of fingerprinting method:Modi-fied Hughes, Landwehr, Distribution and Multi-Discriminant Function. The new methods of reducing the un-certainty of results are to improve the accuracy of the results by increasing the number of samples through statistical analysis or by using a combination of multiple fingerprinting properties. This paper discusses the factors that affect the uncertainty of the results:sediment source areas, sampling methods, and fingerprint-ing properties. At last, an application example is given to compare the new models.
