Abstract

Determining the relative contribution of sediment sources is the first step in planning for soil conservation programs. This study aimed to compare two methods of water sediment source tracing (including fingerprint technique and field measurements of erosion) in Vartavan.catchment. Discriminant analysis and Multivariate mixing model were used for determining the optimum combination of tracers and contribution of sediment sources. Sediment trapper was also used for measuring the erosion of various lithological units. The result showed that the contributions of sedimentary, calcareous and volcanic sources in the outlet sediments were equal to 47. 6, 37. 4 and 15. 1 % respectively and the relative importance of these sources (in terms of specific sediment) were equal to 1. 58, 1. 04 and 0. 48, respectively. The average of minimum and maximum weight of accumulated sediments in trappers were also 2/13 and 6/221 gr for orbitolina and plagioclase limestone. respectively. In total و the results and efficacy of fingerprinting, was approved by field measurements. As well, differences between the results of direct and indirect methods are due to the differences in the area of units and the lack of spatial and filtering resistances in the indirect methods.
