Introducing GEOtop and GEOframe: Open Source Tools for Modeling Snow Dominated Catchments
Co-organized by HS11
Convener: John Mohd WaniECSECS | Co-conveners: Giacomo Bertoldi, Marialaura BancheriECSECS, Matteo Dall’Amico, Giuseppe Formetta

The course is designed for Master’s and PhD students, postdoctoral researchers, and professionals who want to explore open-source models for snow-dominated catchments. It combines theory and practice, introducing participants to hydrological processes in mountain environments and guiding them through hands-on model applications.
Outline:
Introduction: Overview of hydrology in snow-dominated mountain catchments.
GEOframe Modelling System: Introduction to GEOframe’s modular architecture, installation, and a case study demonstration on snow and hydrological modelling in mountain catchments.
Snow Hydrology with GEOtop: Presentation of the GEOtop model, its structure and capabilities, followed by installation and an interactive case study on snow modelling in the Alps.
Discussion: Open exchange, feedback, and wrap-up, with extra resources provided for those interested in further learning.
Learning Goals:
By the end of the session, participants will:
- Understand the key hydrological processes shaping snow-dominated catchments.
- Be able to install, set up, and run basic simulations using GEOtop and GEOframe.
- Join a community of open-source hydrological modelling.
Format & Venue:
Location: EGU 2026, Vienna, Austria
Dates: May 3-8, 2025
Mode: Onsite and virtual, with interactive and hands-on participation.
This short course offers a practical entry point into two widely used open-source hydrological models and a chance to network with peers in the snow hydrology community.
