Decoding geochemical controls and processes illustrating dilution- and baseflow-controlled regimes. (i) Bivariate relationships among major cations and anions. Grey-shaded & transparent panels (ia-p) represent post-monsoon and monsoon samples, respectively. (ii) Diagnostic scatter plots dominant processes: (a) Na/Ca vs. Mg/Ca, (b) Ion-exchange index, (c) TDS vs. (NO3−+Cl−)/HCO3−, (d) Cl− vs. NO3−/Cl−.
