Summary

This dataset contains geochemical data from springs, streams and monsoonal rainwater samples, collected from the Melamchi Valley catchment, Nepal, between 2022 and 2025. The data includes analysis of major ions, stable water isotopes and Sr, Li, Si and C isotopes to investigate chemical weathering along mountain flow paths. Filtered water samples were collected across the Melamchi Valley catchment, with springs grouped into sub-linear transects. Additional time series samples span 2023 to 2025 at bi/weekly sampling at 5 sites.
