Call for abstract - EGU 2026 Session HS2.2.4 Tracer modelling across scales: advancing development, calibration, and process representation in hydrological and water quality models

[Songjun Wu]

Dear all,

We are pleased to invite you and your colleagues to contribute to session HS2.2.4: Tracer modelling across scales: advancing development, calibration, and process representation in hydrological and water quality models at EGU 2026.

Session link: https://www.egu26.eu/session/55912

Our session welcomes contributions that integrate tracers into analysis and modelling to improve understanding of hydrological and biogeochemical processes across spatial and temporal scales. We encourage studies using stable water isotopes, hydrochemical tracers, reactive tracers, biological tracers (e.g., eDNA), or physical tracers (e.g., temperature).

Topics of interest include:

•  Using tracers to explore sources, flow paths, and residence times

•  Tracer-based testing of hydrological and biogeochemical theories

•  Tracer-aided hydrological or water quality modelling (lumped or distributed)

•  Data-driven or hybrid approaches incorporating tracers

•  Tracers for improving parameterization, calibration, and model evaluation

The solicited speaker is Prof. Hilary McMillan from San Diego State University.

We look forward to seeing many of you in Vienna!

Best regards,

Songjun Wu (Leibniz Institute of Freshwater Ecology and Inland Fisheries, Germany)

Paolo Benettin (University of Lausanne, Switzerland)
