Classification of river water quality using multivariate analysis

The classification of river water quality is a useful way of reporting the water quality status of a river to control water pollution in monitored regions. The main objective of this study is to classify the water quality of the Muda River basin (Malaysia) using nine monitoring stations. This study...
