摘要: Characterization of hydrochemistry changes in Johor Straits within 5 years monitoring works was successfully carried out. Water quality data sets (27 stations and 19 parameters) collected this area were interpreted subject to multivariate statistical analysis. Cluster analysis grouped all the into four clusters ((Dlink/Dmax) × 100 1) that explained 82.6% total variance set. Classification matrix discriminant assigned 88.9-92.6% 83.3-100% correctness spatial temporal variability, respectively. Times series then confirmed only parameters not significant over time change. Therefore, it is imperative environmental impact reclamation dredging works, municipal or industrial discharge, marine aquaculture shipping activities be effectively controlled managed.
