Abstract: (7224 Views)
Sediment-related environmental problems pose a serious threat to sustainable land management in many developing countries, including Iran. Information regarding sediment sources represents a key requirement from the management perspective since identification of sediment sources is a precursor to the design of effective sediment management and control strategies. The fingerprinting approach has increasingly been adopted as an alternative to assembling such information. A wide range of fingerprint properties has been used as a means of discriminating potential sediment sources. However, determining the ability of these properties is very important in the design of cost-effective catchment management strategies before each study. This contribution addresses the ability of two acid extractable metals (Co and Cr) that were used extensively in previous studies to be used to differentiate sediment sources. The results of the statistical analysis demonstrate that no single property is capable of classifying the source material samples into the correct source categories at the Amrovan drainage basins. In the case of the Atary drainage basin, Cr and Co were found in only 47.5 and 43.8% of the source material samples respectively. According to the result obtained, it is recommended that acid extractable metals for sediment sources differentiation in conjunction with the composite of other properties to improve sediment source discrimination.
