Factor analysis of hydrochemical data of Kumadvathi river sub-basin in Karnataka, India
Statistical factor analysis (FA) technique has been applied to chemical data of 125 bore well water samples from Kumadvathi river sub-basin to assess the un-usefulness of such techniques for interpretation of the hydro-chemical data. FA technique identified three factors, which account for 60% of the major ion variations observed in the sub-basin, namely, TDS, carbonate and bicarbonate.
