This book addresses the prediction of the Water Quality Index (WQI) at
Perak River, State of Perak, Malaysia, using a fuzzy multiple linear
regression model to tackle the uncertainty in the measurements of six
key parameters - dissolved oxygen (DO), biological oxygen demand (BOD),
chemical oxygen demand (COD), suspended solids (SS), pH value (pH) and
ammoniacal nitrogen (NH3-NL). Given its scope, the book is suitable for
graduate students, researchers and water quality scientists.
