Evaluation on water quality risk based on unascertained mathematics theory of wohushan reservoir

Abstract

Based on unascertained mathematics theory, with unascertained rational number used for single factor quality risk assessment and AHP applied to weight the detection indexes to evaluate the comprehensive risk of water quality on Wohushan reservoir, the calculated results indicated the maximum risk possibility of water quality due to six Pollutants is 0.7368, meanwhile the over standard discharge degree of risk possibility is 73.68%. With the uncertainty characteristics of risk assessment on water quality, the unascertained mathematics theory has better system performance over uncertainty of the parametric information. © 2011 Springer-Verlag Berlin Heidelberg.
