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.

2022 Reactive transport modeling summer institute

Join us Aug 9-12, 2022, in Golden CO for the first Reactive Transport Modeling Summer Institute.  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 with questions.

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.
