Abstract

To investigate the spatial provenance of suspended and bed material sediments in the Taleghani catchment, Lorestan province, western Iran, 11 geochemical tracers were used to distinguish sediment sources. In total, 44 source samples were collected from the surface soil of 3 land use sources and the sub-soil of channel banks together with 8 suspended samples in different flood events, and 11 bed material samples from different river stream sites were also collected. The Collins and Hughes mixing models) were applied to compute the contribution of different sources to both river bed and suspended sediments. Findings reveal the importance of channel bank source. It is highlighted that Hughes mixing model showed a more accurate results, and that uncertainty needs to be accounted for sediment fingerprinting
