Chemical Hydrograph Separation Using Field and Experimental Data with Implications for Solute Cycling in an Alpine Catchment


Geochemical reactions during bedrock fracture flow and in the soil column alter input solute concentrations in the West Glacier Lake catchment. Chemical hydrograph separation provides information regarding the relative importance of geochemical processes. Soil column reactions include cation exchange, anion retention, biotic uptake/release, and mineral weathering. Solute concentrations in precipitation are relatively constant; thus, seasonal concentrations in soil solutions are controlled by cation exchange and anion retendon while net flux of cations from the catchment is the result of mineral weathering.
