Tracking the origin of trace metals in a watershed by identifying fingerprints of soils, landscape and river sediments.

For a better watershed and river water quality management, it is crucial to determine the spatial distribution of soil trace-elements and the contributions of various sources to the sediment yield. More attention has been paid to comprehensive studies of sediment sources and soil trace-elements in connection with suspended sediment production until now. The present study aimed at modeling the spatial distribution of soil trace-elements, determining the sediment sources apportionment, and relating the landforms to polluted soils. For spatial modeling, a total of 79 soil samples with different Nemerow index values were considered. RF had the highest success with an accuracy of 83%, according to the soil trace-element analysis results, with an accuracy of 83%. According to the analysis of polluted soil samples, the landforms'steep hills' and 'valley' contributed the most, with 51% and 27 percent in the riparian zone, respectively.
