Water quality multivariate analysis. Aplication to Júcar river during the 1990-2013 period

Abstract

A study of the Júcar River’s water quality in the period 1990-2013 is performed using multivariate analysis tools. This study is both of longitudinal and transversal nature, ie, water quality is assessed along the river, thus observing the variations in its characteristics during its trajectory from Júcar’s birth to its mouth, and over time, thus detecting changes in its properties and quality over the aforementioned period of time. The use of multivariate analysis tools is also proposed as a way to detect abnormalities in water properties not visible when using univariate techniques, as well as to discriminate when the water being analyzed meets the quality standards.
