Reactive Transport Modeling Hub
An NSF Funded Research Coordination Network
Reactive Transport Modeling Hub
Use of models is increasingly important for the geosciences as the types of data streams and speed of computational capabilities evolve.
For example, new three- and four-dimensional nano- and micro-scale characterization approaches, including micro-computed x-ray tomography (ca. 5-30 micrometer resolution) and full-field transmission x-ray spectroscopy (ca. 2-40 nanometer resolution) are revealing the assembly of earth materials at the pore-scale. Sensor arrays are now measuring gases and some solutes at high temporal and spatial resolution across watersheds, while airborne imaging is revealing geologic and sometimes geochemical structure at meter scales across entire basins.
New modeling approaches enable us to leverage these techniques to evaluate pore scale transport and reaction at the surfaces of individual grains or the consequences of fluid circulation at the watershed scale. Thus, enhancing model literacy is critical for advancing fields of low-temperature geochemistry, hydrology and surface processes that encompass Critical Zone science.
Welcome to the RTM-HUB, an online community to foster communication and integrate community engagement and education around the application of reactive transport models to earth science problems.
Through the RTM-HUB, we aim to create a community-based educational framework for making Reactive Transport Models accessible to the broader community and develop an integrated training platform to address a growing gap between model capability and the user base who can apply them.

2025 Reactive transport modeling summer institute
June 1-5, La Vieille Perrotine CNRS, Ile de Oleron, France
Introduction to reactive transport approaches and models (June 2-4)
Advanced topics in reactive transport and model analysis (June 4-6)
Come for one session or for both!
Participants will learn key skills needed to apply reactive transport models to earth systems, practice creating and interpreting models, and build a network of colleagues in the modeling community. An introductory background in hydrology and/or geochemistry is required, some experience modeling is beneficial. Financial support is available if needed. Email reactivetransporthub@gmail.com with questions.
Applications are closed for the 2025 Workshop
Watch for additional opportunities in the future!

You will be notified of acceptance to the workshop in April 2025 to allow time to secure travel funds and plan travel.
There is no registration fee for the workshop. The only costs to participants are for travel. Funds from NSF will pay for lodging and meals for all participants.
In addition to the following planned workshop topics, you will have time in the workshop schedule to develop the start of your own model. Instructors will be available to help.
