Description

This paper described the estimation of the groundwater flow system based on the principal component analysis of the dissolved major ions data of groundwater and the non-hierarchical cluster analysis of the principal components scores. In Nagara river alluvial fan on Nobi basin, the characterization of groundwater quality was represented by only two principal components. And then, the cluster analysis produced four groups in the relationship between the first and the second principal component scores. When the groups of sampling locations were examined, it was recognized that the groundwater flow could be divided into four systems. The groundwater systems was in good agreement with the one evaluated from groundwater level distribution. Furthermore, the flow system of groundwater recharged from the Nagara river water was specified based on the resemblance of the ions data between the groundwater and the river water.
