the surface water chemistry of thiruvananthapuram museum lake was carried out in the period of february 2013 to january 2014. correlation study of the parameters and overall ccme wqi (canadian council of ministers of the environment water quality index) was also prepared in the study for the lake water. the parameters analysed are cations such as ca2+, na+, mg2+ and k+ and the anions like po4-,...

water quality zoning have been recognized as a useful tool, which gives managers a sweeping view for taking environmental conservative actionsin oeder of priority. ordinary methods, which have been used in iran, involve some defections such as disregard water usage, uncertainty due to sampling error and classification, and changing the class number due to a bit change in water quality parameter...

Estimation of stormwater pollutants is a pre-requisite for the protection and improvement of the aquatic environment and for appropriate management options. The usual practice for the stormwater quality prediction is performed through water quality modeling. However, the accuracy of the prediction by the models depends on the proper estimation of model parameters. This paper presents the estima...

This study presents a method for detecting contamination events of sources of drinking water based on the Dempster–Shafer (D-S) evidence theory. The detection method has the purpose of protecting water supply systems against accidental and intentional contamination events. This purpose is achieved by first predicting future water-quality parameters using an autoregressive (AR) model. The AR mod...
