Abstract

Trend detection of hydrologic da a is useful in the investigation of water quality parameters. In this study, thirty physical-chemical variables on water quality of Perlis River Basin were collected by Department of Environment (DOE) Malaysia from 2003 to 2007 were analyzed using the non-parametric Mann-Kendall Temporal test. Based on this study, the results acknowledged parameter variation over station due to the increasing of Cr concentration and reduction of COD along Perlis River Basin. Correlation coefficients were calculated to identify the strength of the linear relationship between two variables and this unveiled that DS and SS have the strongest correlation.
