benthic macroinvertebrates in river are useful indicators for adverse impacts on the catchment and river ecosystems. these organisms integrate many ecological processes in catchment scale. in this study several single and multi metric biotic indices were used based on macroinvertebrates in order to evaluate the water quality of jajrood river. macroinvertebrates as well as water samples were col...

Zoning the pollution of a river may be the first or even the most important step in water quality management. In order to resolve its pollution, fuzzy clustering analysis may be used whenever a composite classification of water quality incorporates mutiple parameters&#10 &#10In such cases, the technique may be used as a complement or an alternative to comprehensive assessment. In fuzzy cluster...

Based on water quality monitoring data of four inflow rivers of Nansihu Lake in 2006, 2007 and 2008, the water qualities were evaluated according to the method of comprehensive water quality identification index, with the indicators of dissolved oxygen, CODMn, biochemical oxygen demand and ammonia nitrogen. The results show that the rivers has been in the state of serious pollution, in which th...
