The geochemical features of the Ter River watershed (NE Spain)

Abstract

The aims of this paper is to assess the different major ion proportions which define the chemical water type in each sampling-station of the river Ter watershed. Considerations of the relative abundance on the various major ionic constituents of the river is the main subject of discussion. The results show tlÍat application of multivariate statistical techniques may help in clustering the different watershed with similar chemical properties characterized by several abiotic factors. The spatial distribution of major dissolved ions has al so been considered in addition to an approach to determining regional differences in solute levels of the river Ter during low flow conditions.
