Abstract
Implementation of management policies and sediment control is considered requirements. And requires of these programs, identifying and obtaining information about the relative importance of sediment sources and there by identifies critical areas within the watershed. In this study, Sediment deposited in the behind of sediment control structures were studied that constructed on the main channel watershed Nokandeh in Golestan Province. The purpose of this studyis separation of sediment sources with using the tracing method. The first, accordingto available information and maps of the lithology was determined land use, erosion and  slope map units and  in  every  work  unit  were  taken  the  number  of  three sediment  samples.Then  samples  being  analysis  in  laboratory  with  X-ray diffraction  and 9 clay minerals recognized based on statistical methods Kruskal Walis and were evaluated of discriminate function. The results indicate the proper separation of  sediment  sources,  so that  2  clay  minerals  the  Muscovite  and Quartz could have %100 separation sediment sources.  Average of low relativeerror, the high performance coefficient above model and also good consistent results with field observations show that tracers method was utilized in this study, a method is valuable for the separation of sediment sources in the watershed. The reesults also showed that using a combination of tracers characteristics, sediment sources separation rates are significantly higher than any of the individual properties.
