Abstract

This resource provides accompanying discharge and hydrologic data (silicon, sodium, silicon stable isotopes, and discharge and irrigation fluxes) presented in 'Stable Silicon Isotope Fractionation Reflects the Routing of Water Through a Mesoscale Hillslope', Earth and Planetary Letters, https://doi.org/10.1016/j.epsl.2024.119098
This dataset was collected at the Landscape Evolution Observatory (LEO) in Tucson, Arizona from 2022-2023. Discharge chemistry and flux are reported for each of the three LEO hillslopes.

Files are provided in ".csv" format.
