In this paper, we have studied the comparative hydrogeochemistry of the Ken and Betwa Rivers of Bundelkhand area, considering the importance of the Ken-Betwa River linking project (KBLP) in India. Factor analysis and principal component analysis (PCA) has been done to identify the highly correlated and interrelated water-quality parameters. All the physico-chemical parameters for both rivers are within the highest desirable or maximum permissible limit set byWHO (World Health Organization) except some anions viz. NO3-, Cl-, SO42- and F- at some sampling points. The Ken River showed a high spatial variability and significant ionic concentration due to the higher geological and pedological watershed richness as well as absence of pollution from anthropogenic point sources. The Betwa River showed a low spatial variability and higher mineralization due to the anthropogenic point sources that exist downstream. This preliminary study shows the spatiotemporal variability of the hydrogeochemical parameters of the Ken-Betwa River basin.
