From: Entropy and seasonal isotopic duality reveal the sustainability paradox of the upper Ganga River

Seasonal hydrochemistry of the upper Ganga reveals monsoon dilution and post-monsoon solute enrichment. (i) Piper plots showing hydrochemical facies shifts. (ii) Box plots (a–c) summarizing seasonal variability in key parameters. (iii) Longitudinal trends of panels (a–d) for pH, EC, HCO3−, and SO42− (iv) Pearson correlation coefficients for (a) monsoon, and (b) post-monsoon.
