the objective of this study was to diagnose integrative ecological health of an urban stream,which is located in the asian temperate region. the research approach was primarily based on the index ofbiological integrity (ibi) using fish assemblage and a qualitative habitat evaluation index (qhei). and these indexes were compared with long-term conventional chemical dataset during 1996-2005. for ...
Abstract: Water quality assessment is a multivariate nonlinear system. Based on statistical learning theory, support vector machine (SVM) can transform the learning process into a convex quadratic planning problem to get a global optimization by using the rule of minimum structure risk, which is appropriate to solve small-sample, nonlinear classification and regression issues. Applying SVM in w...
Although agenda of Water supply in sufficient quantity and standard quality is highlighted in India from last few years. But Yet Performance assessment and Efficiency evaluation of water supply services not in practice. However the analysis is confined to the realm of researchers and policy makers. The present paper spells inclusion of quality parameter in assessment of utilities through fronti...
the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...
