Abstract One of the consequences of industrial agricultural and urban development is the increase of water pollution Water supply for various consumption has considerable importance in the arid and semi arid regions Development of industries and agricultural activities around the Zayandehrud river where is located in the central plateau of Iran has been caused environmental and ecological problems within Zayandehrud basin Zayandehrud river has been receiving industrial wastewater drained water from agricultural activities as well as urban and village wastewater Surface water quality assessment through permanent monitoring is the base of a program for controlling and decreasing of river pollution Due to their simplicity of application water quality indices WQI can be playing great importance role as one of the methods for determining the water pollution In order to calculate water quality indices NSFWQI BMWP and ASPT as well as richness and biodiversity indices of benthic macroinvertebrates eight stations were selected in Zayandehrud river from Baghbahaderan to Zyar Water and substrate samples were collected monthly from July 2006 to June 2007 The results of Zayandehrud river zoning on the base of NSFWQIm showed that the quality of Zayandehrud water is not acceptable During the period of study 63 5 and 36 5 of calculated data for this index were corresponded to the moderate and poor quality classes respectively Whereas two downstream stations were completely placed in the poor quality class BMWP index classified Zayandehrud river in the moderate and poor quality classes Also according to the Shannon diversity index the river was categorized as moderate and substantial pollution classes Stronger correlation of NSFWQIm with biotic indices BMWP and ASPT in comparison to the richness and biodiversity indices of benthic macroinvertebrates indicates the greater sensitivity of biotic indices relative to river water quality variations In general NSFWQI can be used in Zayandehrud river as a criteria to measure river pollution in a standard manner and also for surveying the improvement trend of river conditions in the future Moreover use of biotic indices accompanied by water quality monitoring is more beneficial but it must be adapted according to conditions of this river Keywords Zayandehrud river WQI Benthic macroinvertebrates Biodiversity Biotic indices pdfMachine is a pdf writer that produces quality PDF files with ease Get yours now Thank you very much I can use Acrobat Distiller or the Acrobat PDFWriter but I consider your product a lot easier to use and much preferable to Adobe s A Sarras USA
