Identifying runoff sources is key to linking hydrology and biogeochemical cycles. We used TraSPAN, a tracer-based streamflow partitioning model, with high-resolution electrical conductivity (EC) and water stable isotope (WSI) data in a forested catchment. EC performed comparably to WSI, highlighting its potential as a low-cost tracer for detailed hydrologic modeling.
